Abstract

See full text

A variable pressure water delivery device having an inlet valve fluidly connected to a reservoir, and connectable to a water supply, the inlet valve is at least operable between an open and closed position. The reservoir has a volume that increases elastically with increasing pressure. At least one outlet valve is fluidly connected to the reservoir and a pressure sensor is actuated by the fluid pressure in the reservoir. A controller receives an output of said pressure sensor and provides control signals to operate said inlet valve according to the output of said pressure sensor, and a desired reservoir pressure parameter.
