Abstract
A flushing apparatus (1, 301) for being installed in the cistern of a toilet including a flushing device (2) for fluid connection with an outlet of a cistern and a hydraulically-driven control circuit (3, 303) for operating the flushing device. The control circuit (3, 303) includes a water inlet (P) for fluidly connecting the control circuit (3, 303) to a source of pressurised water and an accumulator (6) fluidly connected to the water inlet (P) and configured to supplement, in use, the flow of pressurised water supplied by the source trough the control circuit (3, 303) to activate the flushing device (2).
Claims23
A cistern flushing apparatus comprising a flushing device for fluid connection with an outlet of a cistern and a hydraulically-driven control circuit for operating the flushing device, the control circuit comprising a water inlet for fluidly connecting the control circuit to a source of pressurised water, a hydraulically-driven actuator, an operating valve between the actuator and the water inlet for selectively opening fluid communication therebetween and an accumulator fluidly connected between the operating valve and the water inlet, wherein the accumulator is configured to supplement, in use, the flow of pressurised water supplied by the source to the actuator trough the control circuit.
(canceled)
A water supply control circuit for a hydraulic device, the control circuit comprising a water inlet for fluid connection with a source of pressurised water, a water outlet for supplying pressurised water to a hydraulic device, an operating valve fluidly connected between the water inlet and the water outlet for selectively opening fluid communication therebetween, an accumulator fluidly connected between the operating valve and the water inlet, an air inlet for introducing air into the accumulator and a venturi means downstream of the water inlet and in fluid communication with the air inlet for entraining air from the air inlet into the accumulator, wherein the accumulator is configured to supplement, in use, the flow of pressurised water supplied by the source to the water outlet.
