摘要： A stepper motor driven actuator that eliminates the need for a position sensor is provided. The stepper motor rotates a cam in a control piston valve. In a single nozzle embodiment, pressure balance is maintained by a spring preload on one end of the piston in one embodiment, and by hydraulic pressure acting on a double diameter end portion of the piston in another embodiment. As the cam is rotated, the change in the gap between the nozzle and the cam changes the pressures on the control piston ends, which forces the piston in the direction that will re-equalize the pressure based on the cam-nozzle gap. As a result, the head or rod of the actuator piston receives high pressure flow, thereby moving the actuator. Movement of the actuator rod provides mechanical feedback to the cam, causing the cam to move back to its mechanical null position.

摘要： A low energy stepper motor driven fuel metering valve (FMV) that eliminates the need for a position sensor is provided. The stepper motor rotates a cam that replaces the flapper valve used in conventional systems. The cam rotation increases the gap between the cam and nozzle on one side of the cam. The gap difference affects the pressures on the spool piston ends, which forces the piston in the direction that will return the cam-nozzle gap to a distance that results in a pressure balance to return. As a result, the relatively low energy stepper motor controls the relatively high energy hydromechanical system via the cam-nozzle-orifice system. The cam is precision machined and assures stroke/degree gain accuracy. The hydraulic system assures the piston tracks the cam essentially perfectly except for the effects of piston stiction forces.

摘要： An improved distribution valve is provided that distributes water from a swimming pool pump to cleaning heads located along the inner surface of a swimming pool. The distribution valve includes a housing having a fluid inlet and a plurality of fluid outlet ports. The housing includes a lower section and a removable upper section. A gear reduction assembly located in the housing includes a gear reduction mechanism and impeller located near the inlet port and connected to a rotary input shaft of the gear reduction mechanism. A cam device engages a rotary output shaft of the gear reduction mechanism so as to rotate the cam device in response to rotation of the impeller. The cam device rotates under a pliable annular disc on the rotary output shaft and lifts and lowers portions of the annular disc to sequentially open and close fluid paths through the fluid outlet ports.The improved distribution valve may include a bypass chamber with a rotatable drum therein and a diffusion chamber in fluid communication with the fluid inlet. The drum wall includes a cutout. The drum is rotatable to fully or partially align the cutout with a bypass chamber inlet to permit water flow through the bypass chamber to help rotate the impeller. The impeller speed may be controlled by adjusting the water flow through the bypass chamber. The more water flow, the faster the impeller rotates. The drum is also rotatable to block the bypass chamber inlet to prevent water flow through the bypass chamber, in which case water from the diffusion chamber rotates the impeller. Impeller rotation will be at a slower speed due to the decreased water flow.
