摘要： A variable mechanical lubricant pump provides a pressurized lubricant for an internal combustion engine. The lubricant pump includes a delivery port which is fluidically connected to the engine, a control ring which shifts between a maximum and a minimum eccentricity position, a pump rotor having slidable vanes which rotate in the control ring, a control ring preload spring which pushes the control ring into the maximum eccentricity position, a hydraulic control chamber which pushes the control ring into the minimum eccentricity position, a pressure galley pump port fluidically connected to the engine, and an overpressure valve fluidically associated with the delivery port. The pressure gallery pump port charges the hydraulic control chamber with a gallery pressure to control a remote gallery pressure of the engine via a control chamber pressure in the hydraulic control chamber. The overpressure valve opens if an applied lubricant pressure exceeds a predefined maximum pressure limit.

摘要： Disclosed herein is a compressor that includes a compression mechanism configured to suck and compress a refrigerant from a suction space to discharge the refrigerant to a discharge space by driving force transmitted thereto, an oil storage chamber provided in the discharge space to collect oil separated from the refrigerant discharged from the compression mechanism, an oil recovery passage configured to guide the oil in the oil storage chamber to the suction space, and a decompression mechanism provided in the oil recovery passage to reduce a pressure of the oil passing through the oil recovery passage by an orifice hole having an inner diameter smaller than the oil recovery passage, wherein the decompression mechanism is configured such that, when a pressure in the oil storage chamber is increased, the inner diameter of the orifice hole is reduced.

摘要： A compressor for compressing fluid is provided. The compressor includes a housing having a housing inlet for receiving fluid and a housing outlet for discharging the fluid. A compressing mechanism is adapted to compress the fluid toward the housing outlet. The compressing mechanism is disposed in the housing. A drive unit is operatively connected to the compressing mechanism for driving the compressing mechanism to compress fluid. A suction duct is disposed in the housing. The suction duct extends vertically downward from the housing inlet toward a sump defined in the housing. The suction duct is configured for attachment to a motor housing. The suction duct has a duct inlet fluidically connected with the housing inlet, and defines a passage fluidically connecting the duct inlet with an interior cavity of the housing. A suction gas filter disposed in the suction duct, and having a filter screen positioned downstream of the duct inlet.
