Abstract: A spray valve is configured with a fluid path that always provides dynamic water flow on both opposite surfaces of the seating flange of the valve stem when the valve is almost completely closed and when the valve is just beginning to be opened. This equalization of dynamic pressure from the incoming water flow tends to reduce the frequency of vibration that is imposed upon the valve stem and biasing member by the incoming water flow. A check valve is built into the spray valve, which has a trigger lock and a selectively removable spray disk. The valve has an outer sleeve that surrounds the valve's base member and defines a gap therebetween and is formed of mechanical shock-resilient, heat-insulating material.

A hollow adapter sleeve is inserted into the cavity on top of the star lock washer. An O-ring between the exterior of the adapter sleeve and the surrounding sidewall that defines the cavity effects a water-tight fit between the adapter sleeve and the sidewall. The tapered threaded end of the riser is detachably connected to the adapter sleeve by being screwed into the tapered threaded opening of the adapter sleeve.

Abstract: A fluid flow control device is provided as an integral component of a drainage system for sinks in a commercial environment. This fluid flow control device includes a housing that is disposed beneath a waste valve and configured to define a flow control insert that is configured and disposed to interrupt the flow of fluid leaving the waste valve and before that flow reaches a grease interceptor. Both the housing and flow control insert are desirably made as a unitary structure from cast metal. Alternatively, the housing can define a ledge that receives a removable disk forming the flow control insert. In both embodiments, the flow control insert that has an opening through the insert that is sized for a flow area according to the needs of the fluid flows that are anticipated in the drainage system in question.

Abstract: A fluid valve assembly includes a housing, a valve, a rotatable driver received in the housing in operative communication with the valve, and an over-center linkage disposed between the driver and the housing. The housing includes an entrance to permit fluid flow into the housing and an exit to allow fluid flow out of the housing. The valve is disposed between the housing entrance and exit. The valve is configured in an open state to permit fluid flow through the housing and in a closed state to block fluid flow through the housing. Rotation of the driver from a first rotational position toward a second rotational position moves the valve from the closed to the open state, and rotation of the driver from the second rotational position to a third rotational position permits the valve to return to a closed state. The over-center linkage biases the driver to either the first or third rotational position.

Abstract: A fluid valve is provided including a housing having an entrance to permit flow of fluid into the housing and an exit to permit said fluid to flow out of the housing.

A fluid conducting shaft member is disposed through the inlet and outlet member collar sections so that the collar sections rotate about the longitudinal axis of the shaft. A bearing sleeve is concentric about the shaft so that the collar sections rotate about the bearing sleeve. Resilient sealing rings are disposed about the shaft adjacent the bearing sleeve so as to prevent leakage of fluid from the swivel joint. Upon axially compressing the sealing rings and the bearing sleeve together, the sealing rings radially expand thereby sealing against the collar sections.

Abstract: A vacuum breaker is provided comprising a body member having an inlet and an outlet defined therein. A core insert member may be threadedly engaged within the body member having a chamber defined therein. A vent passage is defined within the body member to vent the outlet side of the device to atmosphere. A piston member is movably disposed within the chamber between an upper limit stop and a lower limit stop so as to variably restrict liquid passage through the device. At its lower limit stop, the piston essentially seals the inlet from the outlet while the vent passage vents the outlet to atmosphere. At its upper limit stop, the piston essentially seals the vent passage from the outlet. A drain passage is defined within the device generally between near the top portion of the chamber and the outlet so that liquid entrapped within the chamber above the piston member drains through this drain passage to the outlet side of the device during movement of the piston within the chamber.
