摘要： A hydraulic operating system has a cylinder which is actuated to raise, hold or lower a load against the force of gravity. An electromagnetic 3/2 valve connects a working chamber of the cylinder to a hydraulic reservoir when not energized, and permits flow from a pump to the working chamber when energized. A non-return valve prevents flow from the working chamber to the pump when the valve is energized. A three position switch operates an electric control unit to raise, lower or hold the load in an intermediate position. When holding in an intermediate position, the control unit constantly energizes the valve during a first period, after which the control unit intermittently energizes and deenergizes the valve so as to lower the load in stepwise fashion during a second period.

摘要： A drive assembly for driving a moveable component of a vehicle in which the component can adopt one or more positions in which the component prevents access to the vehicle or a part of the vehicle. The drive assembly has an actuator which is coupled to the component and provides the force for moving the component, and a control unit for actuating the actuator. In an emergency operating mode, the actuator can move freely in at least one direction, in such a manner that the actuator allows movement of the component caused by an external force being exerted on the component other than by means of the actuator, preferably by hand. The drive assembly is also provided with a theft detection unit for detecting theft or attempted theft of the vehicle or of goods which are present in the vehicle. The theft detection unit is coupled to the control unit. The drive assembly is designed so that if the assembly is in the emergency operating mode and the moveable component is in a position in which the component prevents access to the vehicle or a part of the vehicle, and then the theft detection unit detects theft or attempted theft, the emergency operating mode of the drive assembly is cancelled, and the drive assembly is then moved into a blocking mode, in which free mobility of the actuator is cancelled and the actuator blocks movement of the component caused by an external force being exerted on the component.

摘要： The invention provides a variable speed hydraulic pump designed to operate at a maximum horsepower throughout its pressure range by adjusting motor speed according to motor load parameters. In particular, the variable speed hydraulic pump includes a hydraulic pump unit coupled to a variable speed electric motor by a drive unit and to a hydraulic fluid tank for pressurizing and pumping hydraulic fluid when operated by the motor. A motor controller is electrically connected to the motor to supply drive signals to the motor based on electrical characteristics of the drive signals which are dependent on the load exerted on the motor. Suction from the load is provided by both the main pump and a bidirectional supercharging pump by reversing the direction of the motor and shifting a 4/3 valve to connect the main pump inlet to the load and its outlet to tank. In addition, the controller reduces the motor speed at the maximum rated pressure to just maintain the pressure, to reduce the amount of fluid pumped through the maximum pressure relief valve.
