    Abstract: A reciprocating compressor includes a first cylinder and a second cylinder, first and second suction cutoff unloader valve assemblies, and a controller. The first and second suction cutoff unloader valve assemblies are integral to the compressor and are capable of a rapid cycling to interrupt flow of refrigerant to the first and second cylinders. The controller operates at least one of the first suction cutoff unloader valve assembly or second suction cut-off unloader valve assembly in the rapid cycling and monitor a number of rapid cycles. In another aspect, a multi-stage compressor comprises a lower pressure stage and a higher pressure stage, and at least one suction cutoff unloader valve assembly capable of a rapid cycling to interrupt flow of refrigerant to a lower stage cylinder.

    Abstract: 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.

    Abstract: In order to improve a refrigerant compressor for refrigerating systems comprising at least one cylinder unit, which has a cylinder housing and a piston which can move in an oscillating manner in the cylinder housing, a cylinder head, with an inlet chamber, flowed through by an inlet flow of the at least one cylinder unit, and with an outlet chamber, passed through by an outlet flow of the at least one cylinder unit, and a switching valve for interrupting the inlet flow in such a way that it can be operated in any desired part-load range, it is proposed that a control for activating the switching valve is provided, which control, for operating the refrigerant compressor in a lower part-load range, operates the switching valve in successive switching intervals, respectively comprising an opening interval and a closing interval of the switching valve, which are shorter than a shortest time period after which a temperature of an evaporator in the operating refrigerating system has risen by approximately 10% during an interruption of the inlet flow.

    Abstract: A high pressure pump system (14) for use with a hydraulic engine system (10), such as a fuel injection system (10) or a compression release brake system, provides variable delivery of pressurized fluid using sleeve metering principles. The relative position of metering sleeves (56) with respect to pumping pistons (32) is controlled electro-hydraulically by a control circuit (60, 160). The control circuit (60, 160) receives pressurized fluid from the pump delivery gallery (50) or another high pressure area (50, 52) and, using a pressure reducer (64, 164), reduces the operating pressure within the control circuit (60, 160) to a substantially constant pressure lower than the pump output pressure. Lower operating pressure within the control circuit (60, 160) improves the manufacturability of the control circuit components and helps to achieve better control of the pump output.
