摘要： A method of operating a rolling piston compressor includes determining a pressure difference (ΔP) between a discharge pressure (Pd) within a compression volume and a suction pressure (Ps) within a suction volume; determining a pressure ratio (rp) equal to the discharge pressure (Pd) over the suction pressure (Ps); estimating a discharge pressure (Pd) based at least in part on the pressure difference (ΔP) and the pressure ratio (rp); determining that the discharge pressure (Pd) is greater than a predetermined pressure limit (Pd-limit); and lowering a target speed (ωtarget) of the rolling piston compressor.

摘要： An oil supply system for an engine includes a pump body provided with a first outlet port and a second outlet port. The oil supply system further includes a hydraulic-oil-delivery passage, a first oil passage, a second oil passage and a return hydraulic passage. The valve body divides a hydraulic-oil receiving portion for receiving the hydraulic oil in the hydraulic-pressure control valve chamber into a first valve chamber and a second valve chamber. When the hydraulic pressure oil delivered to the hydraulic-oil-delivery passage is in a predetermined value, the hydraulic oil discharged out of the second outlet port is delivered to the hydraulic-oil-delivery passage via the first valve chamber. When the hydraulic pressure delivered to the hydraulic-oil-delivery passage exceeds the predetermined value, the hydraulic oil discharged out of the second outlet port is delivered to the hydraulic-oil-delivery passage via the second valve chamber.

摘要： An oil pump system includes an oil pump, a first hydraulic passage, a second hydraulic passage, a return hydraulic passage, and a control valve. When a revolving speed of a rotor of the oil pump is low, and when a hydraulic pressure of a hydraulic oil, discharged out of a first outlet port of the oil pump to the first hydraulic passage, is lower than a predetermined value, a valve body of the control valve is placed at a first position, thereby joining the hydraulic oil, flowing in the first hydraulic passage, with the hydraulic oil, discharged out of a second outlet port of the oil pump to the second hydraulic passage, and delivering the thus joined hydraulic oil to a hydraulic oil receiving unit via a hydraulic-oil-delivery passage. When the revolving speed of the rotor is high, and when the hydraulic pressure of the hydraulic oil, discharged out of the first outlet port to the first hydraulic passage, is higher than the predetermined value, the valve body is placed at a second position, thereby inhibiting the hydraulic oil from joining, and delivering only the hydraulic oil, discharged out of the first outlet port to the first hydraulic passage, to the aforementioned destination. The oil pump system is downsized and lightweighted advantageously, and is improved in terms of work efficiency and on-boardability.
