摘要： A control system for a variable displacement pump driven by a drive source for driving a vehicle is provided. The variable displacement pump pressurizes hydraulic oil, and is switchable between a full capacity operation in which a discharge flow rate is maximized and a partial capacity operation in which the discharge flow rate is lower than that in the full capacity operation. It is determined whether an operation for starting the drive source has been performed. A rotational speed of the drive source and a temperature of the hydraulic oil are detected. When the rotational speed of the drive source is equal to or higher than a predetermined rotational speed and the hydraulic oil temperature is equal to or lower than a predetermined temperature, immediately after the operation for starting the drive source is performed, the partial capacity operation of the variable displacement pump is performed. This control suppresses generation of untoward noises caused by the operation of the variable displacement pump when starting to drive the vehicle.

摘要： A method for controlling compressor discharge pressure in a compressor. The compressor comprising a compression module driven by a prime mover, the compression module having a discharge port through which a compressed fluid is discharged with a discharge pressure, and an inlet through which uncompressed fluid is flowed into the compression chamber, the flow of fluid through the inlet controlled by an inlet valve repositionable by an actuator driven by a motor. The method comprising the steps of running a discharge pressure control routine, comprising the steps of: calculating the difference between the actual discharge pressure and a predetermined setpoint discharge pressure; computing the required change in valve position to achieve the setpoint discharge pressure, the period of time the motor means must be energized to produce the change in valve position, and the direction the valve must be moved to produce the setpoint discharge pressure. The method including the additional steps of running an actuator position control routine, comprising the steps of: energizing the motor in the required direction for the computed period of time; and braking the motor by energizing the motor in a direction different than the required direction for a braking time interval.
