reference will now be made in detail to the presently preferred embodiments of the invention , examples of which are illustrated in the accompanying drawings . throughout the following detailed description , the same reference numerals refer to the same elements in all figures . throughout this description , for brevity purposes , the term “ spa jet ” will refer to any type of jet for any type of usage , including , but not limited to , spa jets , tub jets , hot tub jets , pool jets , etc . throughout this description , as an example , water and / or air flow through such jets . the term “ water ” refers to a liquid that comprises water ( h 2 o ) and optionally various other dissolved or suspended chemicals and minerals including , but not limited to , pool chemicals , salts , biological materials , dissolved oxygen , suspended sand / dirt particles , etc . the term “ air ” refers to a gas of which our atmosphere comprises having amounts of various gases , suspended particles , water vapor , etc . referring to fig1 , a front perspective view of a jet face 80 is shown . the jet 80 has a face 82 and an exit orifice 86 through which water from the rear of the jet 80 exits . a plurality of side - directed exits 89 is visible . as will be discussed , the side - directed exits 89 provide escapes for water pressure should the exit orifice 86 become impeded . in some embodiments , the fluid channel 84 ( see fig2 ) increases in diameter towards the face portion 82 and exit orifice 86 , although in other embodiments , the fluid channel 84 has a substantially constant diameter . in some embodiments , though not required , the exit orifice 86 has a plurality of directing ribs 91 in the area of the fluid channel 84 where the diameter of the fluid channel 84 increases ( towards the exit orifice 86 in the face portion 82 ). the jet base portion 85 is partially visible , better views of which follow . referring to fig2 , a rear perspective view of the jet 80 is shown with a base portion 85 that interfaces to a jet body 60 as shown in fig3 and 4 . in this example , the back wall 87 is substantially planar to abut a substantially planar spa wall 40 ( see fig3 and 4 ), though curved or angled , or any surface back wall 87 is anticipated . the fluid channel 84 is shown centrally located through an axis of the jet 80 , though any location is anticipated . water is directed through the fluid channel 84 towards the exit orifice 86 in the face 82 . referring to fig3 and 4 , cross sectional views of the jet 80 showing water / air flow when unobstructed ( fig3 ) and when flow is obstructed ( fig4 ) are shown . although , in this example , the spa jet 60 / 80 is shown interfaced to the spa wall 40 using o - ring seals 66 / 68 , this is an exemplary method of mounting and any spa wall interface is anticipated . the interface that is shown has a double o - ring seal 66 / 68 and requires little or no pressure from the spa jet 80 against the spa body 60 to retain this seal because the o - rings 66 / 68 seal between o - ring seats and the inner wall 44 of the formed orifice . the spa jet 60 / 80 has a retainment mechanism ( e . g . a snap , wedge , press - fit , threads , screw , snap , etc .) that retains the spa jet 80 against / coupled - to the spa body 60 . in this example , the jet base 85 threads into the jet body 60 . in the exemplary installation of fig1 , the spa jet body 60 has a substantially tubular insertion area having at least one o - ring seat ( two are shown ). the outer diameter of the tubular insertion area is close to , but less than the inner diameter of the inner wall 44 of the formed orifice , allowing free insertion of the tubular insertion area into the inner wall 44 of the formed orifice ( before addition of o - rings 66 / 68 ). as with most spa jets , the spa jet 60 / 80 has a water inlet 70 and air inlet 72 , though in some embodiments , only a water inlet 70 or only an air inlet 72 is present . the jet 60 / 80 is installed by seating the o - rings 66 / 68 into the at least one o - ring seats , and pushing the tubular insertion area into the formed orifice . the o - rings 66 / 68 compress and apply a sealing force between the o - ring seats and the smooth inner wall 44 of the formed opening . the jet 60 / 80 is held in place by the base 85 of the jet 80 being inserted into the tubular insertion area and locked in place by any retainment mechanism known . as shown , the base 85 of the jet 80 press fits into the tubular insertion area of the jet body 60 . the jet 80 is a self - adjusting jet . the high - pressure water and / or air flows through the fluid channel 84 in the jet body 85 towards the fluid exit 86 in the face 82 of the jet 80 . the fluid channel 84 optionally increases in diameter towards the fluid exit 86 , providing an expansion of the outward flow . the fluid channel 84 is fluidly interfaced at angles ( e . g . right angles ) to a plurality of side - directed fluid orifice 89 preferably situated between the face 82 and the inner wall 87 of the jet 80 . normally , as fluid flows ( e . g . spa water ) unimpeded through the fluid channel 84 , little fluid escapes through the side - directed fluid orifices 89 and most of the fluid is directed out the fluid exit 86 . when the fluid exit 86 is impeded or partially impeded , the fluid pressure is redirected and flows through the side - directed fluid orifices 89 , thereby reducing direct pressure against whatever is blocking the fluid exit 86 and , therefore , eliminating the need to have a pressure adjustment on each oft the jets 60 / 80 . by this mechanism , the jets 60 / 80 are “ self - adjusting ” to accommodate a user 90 laying against the jet 60 / 80 . again , the jets 60 / 80 function with any other spa - jet interface and seal including , but not limited to the exemplary o - ring interfaces , washer interfaces , shoulder washer interfaces , caulked interfaces , combinations of such , etc . as shown in fig3 , there is no restriction of the flow of water through the fluid exit 86 and , hence , most of the water flow is directed outwardly ( e . g . towards a user ). in fig4 , the fluid exit 86 is blocked or at least partially blocked , for example , by a person 90 resting against the spa jet face 82 . if not for the side exits 89 , the water pressure would continue to push through the fluid exit 86 and provide discomfort to the person 90 , possibly causing bodily harm to the person 90 . when the fluid exit 86 is blocked or impeded , some or all of the fluid / water is directed out of the plurality of side exits 89 and the pressure from the exit 86 is minimized . equivalent elements can be substituted for the ones set forth above such that they perform in substantially the same manner in substantially the same way for achieving substantially the same result . it is believed that the system and method as described and many of its attendant advantages will be understood by the foregoing description . it is also believed that it will be apparent that various changes may be made in the form , construction and arrangement of the components thereof without departing from the scope and spirit of the invention or without sacrificing all of its material advantages . the form herein before described being merely exemplary and explanatory embodiment thereof . it is the intention of the following claims to encompass and include such changes .
a spa / tub jet is disclosed including a jet base portion and a face portion and having a channel extending through the jet base portion and through the face portion at a fluid exit . a plurality of side - directed fluid orifices is included . each of the side - directed fluid orifices is in fluid communications with the channel . to reduce pain to a user who moves their body too close to the spa / tub jet , as the user &# 39 ; s body impedes a flow of water out of the fluid exit orifice , water pressure is directed out of the side - directed fluid orifices .
