A device for moving a cleansing nozzle connected to a water supply system includes an elongated nozzle, a cylinder in which the nozzle is axially slidable, a motor having an output shaft, a drum body mounted on the output shaft, the drum body having a cylindrical rim surface and a sectoral recess extending from the surface, a sectoral insert disposed in the recess and having a partial cylindrical surface conforming to and forming a continuation of the cylindrical rim surface, and a leaf spring having one end connected to the nozzle and the other end held between the drum body and the sectoral insert such that rotation of the drum body extends and withdraws the nozzle longitudinally as the leaf spring unwraps and wraps around the drum body. The method includes counting the number of cycles of the frequency of the electric power supplied to the motor, determining the actual position of the nozzle on the basis of the counted pulses, establishing a predetermined position of the nozzle, comparing the actual position with the predetermined position, and transmitting the results of the comparison to a power circuit for the motor to turn the motor on and off so that the motor thereby positions the slidable nozzle at the predetermined position.
A device for moving a cleansing nozzle connected to a water supply system comprising an elongated nozzle, a structure having a cylinder in which said nozzle is axially slidable, a motor mounted on said structure, said motor having an output shaft, a drum body mounted on said output shaft, said drum body having a cylindrical rim surface and a sectoral recess extending from said rim surface, a sectoral insert disposed in said recess and having a partial cylindrical surface conforming to and forming a continuation of said cylindrical rim surface, and a leaf spring having one end connected to said nozzle and the other end held between said drum body and said sectoral insert, whereby rotation of said drum body extends and withdraws said nozzle longitudinally as said leaf spring unwraps and wraps around said drum body.
A method of controlling the position of a slidable nozzle connected to a water supply system wherein the nozzle is lfngitudinally slidable in a cylinder by a leaf spring which has one end connected to the nozzle and the other end mounted on and operative to wrap about a drum driven by a synchronous motor, the method comprising the steps of counting the number of cycles of the frequency of the electric power supplied to said synchronous motor, determining the actual position of said nozzle on the basis of said counted pulses, establishing a predetermined position of said nozzle, comparing said actual position with said predetermined position, and transmitting the results of said comparison to a power circuit for said motor to turn said motor on and off so that the motor thereby positions said slidable nozzle at said predetermined position.
