Abstract: A fluid dispenser pump actuated manually to dispense a metered quantity or “dose” of fluid each time it is actuated. The pump has a pump body containing a pump chamber and a return spring resiliently urging the pump towards its rest position and returning it automatically to the rest position after each actuation. The pump chamber has an outlet value that is urged towards a closed position by the pressure from the fluid while the pump is being actuated, and is opened mechanically by a valve control element at the end of actuation. Once the full dose has been prepared, the outlet valve is kept in the open position while the fluid is expelled from the pump chamber. This prevents the flow of fluid from closing the outlet valve again before the full dose of fluid has been expelled.

The valve member is suitable for use in particular in thermostat valves.

Abstract: The comestible fluid dispensing system of the present invention preferably employs a pump or valve operable to control movement of comestible fluid from a comestible fluid source to a tap provided with a draw-back valve. The draw-back valve is preferably capable of drawing comestible fluid in an upstream direction in the tap during closure of the draw-back valve. Preferably, suction generated by closure of the draw-back valve is employed for one or more purposes including: to remove comestible fluid dangling from the tap, to draw comestible fluid into the tap away from view and from exposure to the environment, to reduce comestible fluid buildup on and near the tap outlet, to enclose or at least partially enclose comestible fluid downstream of the draw-back valve, and to operate a downstream cutoff valve in the tap. A damper is employed in some embodiments to control valve movement.

Abstract: A valve for controlling fluids having an actuator unit for actuating a valve member, which has a first piston and a second piston, separated from it by a hydraulic chamber, and which actuates a valve closing member that divides a low-pressure region at system pressure from a high-pressure region. For leakage compensation, a filling device connectable to the high-pressure region is provided with a hollow chamber, in which a throttle body is disposed such that a line leading to the high-pressure region discharges into the hollow chamber on one end of the throttle body, and on the other end a system pressure line leading to the hydraulic chamber branches off. The system pressure is built up by geometric definition of a throttle bore in the throttle body and of the dimensions of the piston, along which the system pressure is reduced, as a function of a prevailing pressure in the high-pressure region.
