Abstract: A water conservation device for lever actuated faucets having a pair of donut-shaped rings formed of a non-abrasive material, the apertures of the donut-shaped rings of such a dimension that they are slidably received onto a faucet head of a faucet associated with a sink and the lever of the faucet which activates the flow and termination of water, the pair of donut-shaped rings having secured there between a length of expandable/retractable band fabricated from suitable material which is expandable and stretchable upon upward pressure on the lever handle of the faucet to allow the lever handle to open the valve and initiate the flow of water, the retractable band having sufficient elasticity to exert downward pressure on the lever moving the lever downwardly to close the valve and terminate flow.

Abstract: A handle (2) as actuating device for valves (1) is proposed, comprising a fastening head (10) for fastening to a spindle (7) of the valve (1) and an actuating arm (11) for rotatably actuating the spindle, the spindle (7) being arranged in a valve housing (5) so as to be rotatable about the axis of rotation of a sealing part, the actuating arm (11) being arranged to be movable perpendicularly to the axis of the spindle (7) from a closed position into an open position of the valve (1). The actuating arm (11) has means (14) for preventing the actuation of the handle (2), the fastening head (10) has a fastening means (21) for fastening the handle (2) to the valve spindle (7), and the handle (2) has a sealing plate (15) for sealing the fastening means (21).

Abstract: A child resistant tap has a valve body (12) with an inlet (22) and an outlet (24) and a valve seat (26) therebetween. An axially slidable valve element (28) engages the valve seat (26) to open and close the valve. A handle or lever (1) is pivotally connected to the valve element (28) outside the valve body. The handle has a fulcrum portion (1-2), so that pivotal movement of the handle (1) operates the valve element (28). A safety lever (6) is pivotally attached to the handle (1) and has a locking arm (6-2) which engages the valve body (12) to prevent the handle from pivoting to open the valve. The safety lever (6) also has an actuator arm (6-1) located adjacent to a transverse lever arm (1—1) of the handle, so that squeezing together of the actuator arm (6-1) and the handle lever arm (1—1) causes the safety lever (6) to pivot out of engagement with the valve body (12) allowing the valve to be opened.

Abstract: A motor providing safety actuation including a spring which, during the power outage, is designed to close a valve by moving a valve cone towards a valve opening. For installation or transportation of such valves with motors, it is desirable to lock the valve actuation rod. A device is described for securing a resilient locking element to the valve cone which is mounted on a valve actuating rod. In the desired installation position, the locking element is in a force-transmitting engagement with a guide mechanism of the actuating rod so as to lock the actuating rod in a position or, alternatively, engages in a formfitting manner with a recess of the guide mechanism of the actuating rod. To secure the actuating rod in position in a force-transmitting or formfitting manner, the motor is powered until the valve actuating rod is sufficiently retracted. Subsequently, a mechanical connection is established between the resilient locking element and the guide mechanism of the actuating rod.

Abstract: A fluid flow control valve is provided comprising a valve seat inside a housing for defining a passage opening in the housing and a valve seal positioned against the valve seat for closing off fluid flow. A push rod extends from the valve seal and through the passage opening. The push rod is moveable for moving the valve seal off the seat to open the valve. The valve seal is restricted to substantially axial movement, preferably by a spring biasing the valve seal against the valve seat which spring is sized so as to engage the walls of the passage. A cam shaft rotatably mounted in the housing is provided for moving the push rod upon rotation of the cam shaft. A handle is non-rotatably connected to the shaft for rotating the cam shaft. A latch may be provided for releasably locking the handle in a position where the valve is open. A safety may also be provided on the latch arm so as to prevent the handle from being moved accidentally.

Abstract: An adjustment control for a thermostatic valve consists of a non-rotatable component to the valve on which is mounted a rotatable knob for setting the temperature control, the knob having a maximum rotation of about one revolution. A releasable auxiliary device is provided which is operable between the component and the knob at a predetermined intermediate rotational position of the knob to limit the rotation of the latter.
