ABSTRACT:
A hygienic device has a pump for propelling liquid in a flow of pulses, a motor for driving the pump, a switch for supplying power to the motor and means for delivering the propelled liquid to a point of use. A control enables adjustment of the pressure of the delivered liquid. The switch is formed as part of the motor winding assembly and therewith is effectively encapsulated. The pump includes a piston in one end of which is a recess defining a resilient spherical seat and which cooperates with a spherical bearing formed on one end of a piston rod. The control has a valved bypass arrangement wherein various stops and abutments cooperate to permit accurate determination of high and low pressure adjustment during assembly. A rotor within the motor has a cylindrical bore with longitudinal lugs that interfit with ribs on a bearing member that is pressed into the bore. Other features, such as a tilt-out nozzle storage shelf, are included.
