摘要： An automotive air conditioning apparatus includes an input shaft connected to an engine, a pump unit disposed on the input shaft, a compressor unit disposed on the input shaft, and a separator wall disposed between the pump unit and the compressor unit and adapted to seal therebetween in the axial direction of the input shaft. The pump unit includes a first short-circuiting passage communicating the suction space and the discharge space, and the first short-circuiting passage is provided with a first control valve. The compressor unit includes a second short-circuiting passage communicating the suction area and the discharge area, and the second short-circuiting passage is provided with a second control valve. When heating, the first short-circuiting passage is closed with the first control valve, and the second short-circuiting passage is opened with the second control valve to disable the compressor unit. When cooling, the first short-circuiting passage is opened with the first control valve to disable the pump unit, and the second short-circuiting passage is closed with the second control valve.

摘要： An axial piston pump, for pumping an operating oil in a hydraulic system, comprises a rotary cylinder block having a plurality of cylinder bores formed therein and disposed at regular intervals around a rotational axis thereof. Each bore is opened at a bottom thereof through a hole formed in an end wall of the cylinder block, a plurality of pistons being slidably received in the bores, respectively. Further, the pump comprises a fixed slant cam plate engaged with the pistons during a rotation of the block, for causing a reciprocation of the pistons within the cylinder bores, and a fixed valve plate having a suction port and a discharge port. The block end wall is resiliently pressed against the valve plate so that the holes of the bores are operatively connected with the suction and discharge ports of the valve plate during the rotation of the block. The valve plate has an annular seal land formed thereon and surrounding the ports, to thereby form an annular oil groove around the annular seal land, and a plurality of bearing lands formed at regularly spaced intervals along a periphery of the valve plate member, to thus form a radial oil passage between two adjacent bearing lands. The radial oil passage is at least partially defined by a cylindrical surface or sloped surface so that a penetration of the operating oil from the radial oil passage into a fine space between the bearing lands and the cylinder block end wall.
