摘要： An oscillating piston compressor includes two oscillating compression units, and an introduction section configured to introduce an intermediate-pressure refrigerant into a compression chamber of each of the compression units. Each compression unit has a cylinder forming a cylinder chamber, a piston housed in the cylinder chamber, and a blade integrally formed with the piston. The piston rotates in the cylinder chamber while the blade oscillates. The two compression units are configured such that phases of the pistons are opposite to each other. The piston has a non-circular outer peripheral surface, and the cylinder chamber has an inner peripheral surface with a shape determined based on an envelope of the outer peripheral surface of the piston in rotation.

摘要： A rotary compressor includes a cylinder having a cylinder chamber and bush groove, a piston housed in the cylinder chamber, a blade formed with the piston to separate the cylinder chamber into low and high pressure chambers, and a pair of bushes. The bushes are fitted in the bush groove with flat surfaces facing each other to hold the blade. The flat surface of at least the bush on the low-pressure side has a crowned portion starting from a position closer to the back pressure space than a swing center position, and extending toward an edge of the bush closer to the cylinder chamber. The swing center position is where a gap between the blade and the bush is constant while the piston rotates eccentrically.

摘要： A device usable as an impeller has a plurality of vanes rotating eccentrically about a shaft. Eccentric rotation is enabled by a cam mounted on the shaft. The vanes are received within slots in a rotor which surrounds the shaft and rotates about an axis coaxial with the shaft. The rotor rotates within a housing having a cylindrical surface facing the rotor. The surface is eccentric to the shaft. The vanes execute reciprocal motion upon rotation of the rotor. The vane motion is constrained so that the edges of the vanes remain proximate to the cylindrical surface during rotation.

摘要： A fuel vapor treatment apparatus of a vehicle in which a supercharger that supercharges intake air is provided at an intake passage of an internal combustion engine includes a pump controller that drives a pump, a gas passage pressure detector that is provided between a canister and the pump in a gas passage and detects pressure of the gas passage, and an abnormality determining module that determines whether an upstream-side purge passage has an abnormality, on the basis of the pressure detected by the gas passage pressure detector. The pump controller drives the pump when an upstream-side valve is in an opened state. The abnormality determining module determines whether the upstream-side purge passage has an abnormality, on the basis of the pressure detected by the gas passage pressure detector after the upstream-side valve enters the opened state and the pump is driven.
