摘要： A linear actuator system includes a linear actuator and at least one proportional control valve and at least one pump connected to the linear actuator to provide fluid to operate the linear actuator. The at least one pump includes at least one fluid driver having a prime mover and a fluid displacement assembly to be driven by the prime mover such that fluid is transferred from the pump inlet to the pump outlet. The linear actuator system also includes a controller that establishes at least one of a speed and a torque of the at least one prime mover and concurrently establishes an opening of the at least one proportional control valve to adjust at least one of a flow and a pressure in the linear actuator system to an operational set point.

摘要： A method for operating a liquid ring vacuum pump employs taking vibration measurements of the pump and comparing the measurements with a prescribed cavitation threshold. In addition, a measurement representing the liquid content in the gas to be conveyed is taken. This measurement is compared with a prescribed threshold. The rotational speed of the liquid ring vacuum pump is reduced if the prescribed cavitation threshold has been exceeded and the liquid content is less than the prescribed threshold. The rotational speed is increased if the prescribed cavitation threshold has been exceeded and the liquid content is greater than the prescribed threshold. A liquid ring vacuum pump is designed for implementing the method. Due to the regulation depending on the oscillations of the pump, the pump can be operated near the cavitation boundary without any risk of damage.

摘要： In an electric-motor-driven oil pump unit with automatic engine-stop system interaction, in which an electric-motor-driven oil pump is driven by an electric motor for hydraulic pressure supply to a transmission of an automotive vehicle employing an automatic engine-stop system, at least in a stopped state of a mechanical oil pump driven by the engine, a motor current/speed detector is provided for detecting a motor current and/or a motor speed of the electric motor. Also provided is a controller configured to output an inhibiting signal to the automatic engine-stop system for inhibiting a mode shift to an automatic engine-stop mode, when a change in the motor current and/or the motor speed during a preliminary operation of the electric-motor-driven oil pump executed from a point of time when an automatic engine-stop condition of the vehicle becomes satisfied, is out of a specified characteristic.

摘要： A compressor system operable to shutdown in response to a shutdown signal. The compressor system includes a compression device operable between a first speed and a second speed to produce a flow of compressed fluid at a pressure. A blowdown valve is movable between a closed position and an open position in which at least a portion of the flow of compressed fluid passes through the blowdown valve to reduce the pressure of the flow of compressed fluid. A sensor is positioned to measure the pressure and a controller is operable to move the blowdown valve to the open position and set the speed of the compression device to a low set point speed in response to the shutdown signal.
