    摘要： A pump for an engine includes a suction chamber, a discharge chamber, and a piston at least partly received within a relief chamber. The piston has first and second passageways provided therein. The second passageway is located closer to a face of the piston than the first passageway. The piston is movable within the relief chamber, so that the volume of the fluid transfer from the suction chamber to the discharge chamber is varied according to a pressure in the relief chamber. The first and second passageways form fluid paths between the suction chamber and the discharge chamber at a first and second pressure in the relief chamber, respectively, the first pressure being less than the second pressure.

    摘要： An air compressor comprising: a tank (50), a compression mechanism (30), a motor (5) and a control circuit (7). The control circuit (7) includes a CPU (70) and a storing unit (74) which stores a control program, the compressor operation history and a plurality of operation modes. Each of the operation modes is defined by two setting values: a reference restart pressure value and a motor rotational speed value, at least one of these values being different from among the plurality of modes. The control circuit (7) executes one of the plurality of modes as a target mode in which the control unit controls the motor to restart by comparing the pressure in the tank with the reference restart pressure and rotates the motor at the rotational speed of the target mode. The control circuit changes the target mode from the one of the plurality of modes to another one of the plurality of modes based on the compressor operation history.

    摘要： A system is provided and may include a compressor operable in a refrigeration circuit. A first sensor may detect high-side data indicative of an operating condition of a high-pressure side of the refrigeration circuit and a second sensor may detect low-side data indicative of an operating condition of a low-pressure side of the refrigeration circuit. Processing circuitry may receive the high-side data and the low-side data from the first and second sensors and may process the high-side data and low-side data to determine at least one of a low-side fault and a high-side fault. The processing circuitry may operate the compressor in a normal mode in the absence of a low-side fault and a high-side fault and may operate the compressor in a reduced-capacity mode or a shutdown mode based on a severity of the at least one of the low-side fault and the high-side fault.

    摘要： An operational control device is disclosed for a positive-displacement pump having a motor, means for actuating the motor, state sensor means for detecting an actual operating parameter (e.g., pressure) of the pump, and operating mode means for controlling an operating mode of the pump. A first actuating mode of the operating mode means is set by the actuating means below a first operating-parameter threshold value (P1). This mode brings about a constantly rising pump pressure in the direction of an operating-parameter setpoint value (Pset) in a variable manner, which is dependent on a detected change in the operating parameter over a predefined time interval. A second actuating mode is set as normal operation to the operating-parameter setpoint value by the actuating means above the first operating-parameter threshold value. P1 is fixed or is calculated as a fraction of the operating-parameter setpoint value and/or a pump parameter correlated therewith.

    摘要： A method of controlling the loading and unloading of a compressor includes selectively loading and unloading a compressor by engaging and disengaging, respectively, compressor members with the controller in response to system load data, monitoring at least one of the discharge pressure and the suction pressure at a predetermined time interval for a continuous time period, storing values based on the at least one of the discharge pressure and the suction pressure during the continuous time period, and determining a predetermined value indicative of compressor operation in which the compressor members are engaged. The method further includes comparing at least one of the stored values with the predetermined value and providing a signal to cease operation of the compressor when the comparison fails to indicate compressor operation in which the compressor members are engaged.

    摘要： An exemplary pump includes a pump housing defining a pump cavity, a movable pumping member situated in the pump cavity, and at least one pressure-absorbing member located inside the pump housing. The housing also has an inlet and an outlet, and includes at least one interior non-wearing location that contacts liquid in the pump housing when the pump housing is primed with the liquid. The movable pumping member, when driven to move, urges flow of the liquid from the inlet through the pump cavity to the outlet. The at least one pressure-absorbing member is located inside the pump housing at the non-wearing location and contacts the liquid. The pressure-absorbing member has a compliant property to exhibit a volumetric compression when subjected to a pressure increase in the liquid contacting the pressure-absorbing member, the volumetric compression being sufficient to alleviate at least a portion of the pressure increase.
