Abstract: A vehicle air conditioner has a blowoff mode door provided at a position where a rear seat blast passage is branched into a vent blowoff passage and a foot blowoff passage, and the blowoff mode door has a main door portion and a sub-door portion. The blowoff mode door is displaced by rotation among positions: a full-closed mode position where both the blowoff passages are closed; a vent blowoff mode position where the vent blowoff passage is opened and the foot blowoff passage is closed; a foot blowoff mode position where the vent blowoff passage is closed and the foot blowoff passage is opened; and a bi-level position where both the blowoff passages are opened.

Abstract: A gas compressor includes at least two first and second discharge ports (45a, 45b) which are provided at an upstream side in a rotation direction of a rotor (50) along a peripheral direction of an inner peripheral surface 40a of a cylinder (40) with respect to a closest area (proximity part (48)) where the inner peripheral surface (40a) of the cylinder (40) and an outer peripheral surface (50a) of the rotor (50) are closest in a range of one revolution of a rotation shaft (51) and configured to discharge the refrigerant gas compressed in compression chambers (43). Of the first and second discharge ports (45a, 45b), on only the first discharge port (45a) closest to the proximity part (48), a cutout groove portion (47) is provided at a downstream-side edge portion of the first discharge port (45a) in the rotation direction of the rotor (50).

Abstract: A gas compressor includes a cylinder block, a rear side block, a front side block, a cylinder chamber segmented by the above three blocks, a rotor provided in the cylinder chamber, vane slots formed on the rotor, vanes inserted into the vane slots, and a suction hole provided on at least one of the front and rear side blocks. Refrigerant is suctioned into the cylinder chamber from the suction hole. An opening edge of the suction hole is composed of an in-chamber opening edge that locates within the cylinder chamber and an in-block opening edge that faces to a sidewall of the cylinder block. The in-chamber opening edge locates on a side of an oval inner wall away from an outer circumference of the rotor. According to the gas compressor, leaning of the vanes is restrained, so that ground damage or attrition of the blocks, vibrations and noises are restrained.
