| 15 | Method of operating a pumping system | US11992684 | 2006-09-20 | US09334864B2 | 2016-05-10 | Anthony John Wilder |
| A pumping system has a motor (32) for driving a pumping mechanism (30). A variable frequency drive unit (36) has an input for receiving electrical energy of relatively high power and first, fixed frequency from a power supply, and an output coupled to an input (46) of the motor for supplying electrical energy of relatively low power and second, variable frequency to the motor. This second frequency preferably has a maximum value greater than the first frequency. A control circuit (50) is provided for selectively coupling the motor input (46) directly to the power supply for the supply of the relatively high power energy to the motor to maximize the torque that can be produced by the pumping mechanism. After a period of time the control circuit terminates the direct coupling of the motor input to the power supply for the supply of the relatively low power energy to the motor. | ||||||

| An electrical pump apparatus is provided in which a situation where a failure detection circuit becomes inoperative before detection of a failure of an electric system can be avoided, and the certainty of failure detection can be enhanced. An attaching portion which is to be attached to a vehicle body is formed so that, in a state where an electrical pump apparatus is attached to the vehicle body, a circuit board of a control device is perpendicular to the horizontal direction. A control IC chip which constitutes a microcomputer for detecting a failure of the electric system is placed on a circuit board so as to be higher in the direction of gravity from a lowest water level Hmin at which flooding in a housing causes the electric system to be short-circuited. | ||||||

| 19 | Variable displacement pump having throttled control passages | US580187 | 1995-12-28 | US5562432A | 1996-10-08 | Fusao Semba; Kenya Yasui |
| To restrain the swinging of a movable displaceable cam ring and a spool of a control valve and to suppress pulsation on the discharge side of a variable displacement pump. In the variable displacement pump, a variable metering orifice (40) is provided midway in discharge-side passages (24, 29, 43, 44, 45) extending from a pump chamber. A spool-type control valve (30) is operated with the fluid pressure on the upstream and downstream sides of the orifice to control the fluid pressure supplied to fluid-pressure chambers around the cam ring in accordance with the flow rate of the fluid discharged from the pump chamber. A single or multistage throttle portion including throttles (50, 51, 52) is provided in at least one of fluid passages (46, 47) for communicating the upstream side of the orifice to one chamber of the valve, and fluid passages (35, 19b) for communicating the one chamber to the first fluid-pressure chamber as the valve operates. | ||||||
| 20 | Micro-processor control of compression ratio at full load in a helical screw rotary compressor responsive to compressor drive motor current | US659039 | 1984-10-10 | US4519748A | 1985-05-28 | David A. Murphy; Peter C. Spellar |
| An axial flow helical screw type compressor has a slide valve member and slide stop member mounted end to end beneath the intermeshing rotors such that the slide valve member controls communication between the work chamber defined by the rotors and the casing to the outlet port and the slide stop member and the valve member together control the working fluid inlet to the bores of the rotors, the slide valve member and the slide stop being independently movable. Control means for the slide valve member and slide stop include position sensing means for these two members, inlet and outlet pressure sensing means, and means for feeding these inputs into programmable circuitry to control the positions of the slide member and slide stop. Additional control means senses the occurrence of full load operation and then causes the slide valve member and slide stop member to move as a closed unit in a given direction, or the reverse, as the compressor drive motor current is sensed, continuously seeking the position at which such current is at a minimum. | ||||||
