Abstract
Abstract A liquid injector system for introducing, metering, and premixing a liquid hygienic agent such as soap or medicant into a stream of water flowing through a conduit for dispensing in a bath or shower array of spray nozzles. The system includes at least one manually operated piston valve mounted in the water flow line to the spring nozzles and include communication with an agent injector cylinder having a dispensing system actuated by system water pressure. The valve includes a housing with a water flow-through, direction reversal chamber in fluid communication with the reciprocally movable valve body having an axial passage terminating in a radial passage near a mid-portion of the valve body. The system ensures for positive metering and thoroughly mixing the agent in the spray system.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
230 words
A system for injecting a first liquid into a second liquid stream such that the first liquid and second liquid are mixed thoroughly together in metered quantities, comprising: a valve housing, said housing having at least one chamber for receiving a valve body, said housing including an inlet passage for receiving said first liquid, said housing further including an inlet and outlet passage for receiving said second liquid, said second liquid inlet and outlet passages being in fluid communication with said valve body chamber; a valve body disposed moveably within said valve body housing chamber, said valve body including a land area disposed around its perimeter, the diameter of the land being less than the diameter of said valve body chamber; first and second sealing means each disposed on an opposite side of said valve body land; said valve body including an interior passage providing fluid communication between the surface of said land and the base of said valve body; means connected to the bottom of said valve body chamber and contacting the bottom of said valve body for resiliently holding said valve body in a first position; said second liquid inlet and outlet means having substantially parallel longitudinal axes, said valve body being moveable to a second position whereby said land area on said valve body is in fluid communication with the first liquid inlet passage in said housing.
Claim 2
Independent Claim
230 words
A system for injecting a first liquid into a second liquid stream such that the first liquid and second liquid are mixed thoroughly together in metered quantities, comprising: a valve housing, said housing having at least one chamber for receiving a valve body, said housing including an inlet passage for receiving said first liquid, said housing further including an inlet and outlet passage for receiving said second liquid, said second liquid inlet and outlet passages being in fluid communication with said valve body chamber; a valve body disposed moveably within said valve body housing chamber, said valve body including a land area disposed around its perimeter, the diameter of the land being less than the diameter of said valve body chamber; first and second sealing means each disposed on an opposite side of said valve body land; said valve body including an interior passage providing fluid communication between the surface of said land and the base of said valve body; means connected to the bottom of said valve body chamber and contacting the bottom of said valve body for resiliently holding said valve body in a first position; said second liquid inlet and outlet means having substantially parallel longitudinal axes, said valve body being moveable to a second position whereby said land area on said valve body is in fluid communication with the first liquid inlet passage in said housing.
Claim 3
Dependent Claim
24 words
An injector system as in claim 1, including: a means connected to said valve housing for stopping said valve body in a predetermined position.
Claim 4
Dependent Claim
63 words
An injector system as in claim 1, including: a receptacle for housing said first liquid; a floating piston disposed within first liquid receptacle; inlet means connected to said receptacle on one side of said piston for receiving said second liquid under pressure; outlet means disposed on the opposite side of said piston connected to the first liquid inlet passage in said valve housing.
Claim 5
Dependent Claim
31 words
An injector system as in claim 3, including: means connected to said valve housing and said valve body for moving said valve body from a first position to a second position.
Claim 6
Dependent Claim
33 words
An injector system as in claim 4, wherein: said valve body resilient positioning means includes a means for providing fluid resistance disposed in fluid communication with said second liquid inlet and outlet means.
