    摘要: Air-demand-controlled compressor arrangement, particularly for commercial vehicles, includes a motor unit for generating a rotating movement which, by way of an interposed rotational-speed-transmitting transmission unit, drives a compressor unit for generating compressed air from ambient air. A control unit triggers the generating of compressed air in the case of a compressed-air demand. The transmission unit is constructed in the manner of a transmission whose rotational speed can be varied, and the control unit interacts with the transmission unit in order to adapt the rotational speed of the transmission unit corresponding to the compressed-air demand.

    摘要: A fluid pump is provided that produces an outflow of fluid that is not proportional to the speed of the input drive. Thus, the fluid pump can be tuned to provide a substantially constant outflow of fluid irrespective of the speed of the input drive. The fluid pump also provides fluid outflow when the rotational direction of the input drive is reversed.

    摘要: The speed of a pump motor in a vehicle brake control system is controlled by comparing an actual pump motor speed to a threshold speed. The actual pump motor speed is determined by measuring the pump back emf while the motor is de-energized. If the actual pump motor speed is greater than the threshold speed, the motor remains de-energized. If the actual pump motor speed is less than the threshold speed, the pump motor is energized with a pulse width modulated voltage having a variable duty cycle and a variable frequency which are functions of the difference between the actual pump motor speed and the threshold speed.

    摘要: A system for detecting leaks in a hydraulic system. The system shuts down the hydraulic system if a leak is detected and notifies individuals in the area that a leak has occurred. The leak detection system has sensors for measuring hydraulic system parameters and a computer for detecting abnormalities in the system based on values returned by the sensors. Sensors used in the example leak detection system include an RPM pickup, a pressure transducer, a flow meter and an hydraulic fluid level and temperature switch. Outputs of the sensors are analyzed by the computer to determine if the hydraulic system has a leak. If a leak is detected, the computer sends response signals to a device for engaging or disengaging the prime mover from the hydraulic pump and to another device for actuating a valve to stop hydraulic fluid flow from the reservoir. The computer may also send indicator signals to a display console for activating a warning light, a buzzer or a display.
