<p>PURPOSE:To prevent a pressure loss by a small sized constitution by forming a recessed part, connected to a suction gas passage, in an axial directional end face in a pair of cylinder blocks, so as to eliminate reducing a flow path sectional area even when the suction gas passage is arranged in the vicinity of a rotary shaft. CONSTITUTION:A pair of cylinder blocks 1, 2 are arranged so that the axial center agrees with a space provided in each other in a single axial direction. Here, in one end side in the axial direction in each cylinder block 1, 2, that is, in an end face in a swash plate chamber side, so as to connect end parts of a plurality of suction gas passages H, an annular recessed groove 30 annularly extended in the periphery of a rotary shaft 4 is formed. By the annular recessed groove 30, a flow path sectional area in the vicinity of the end part of each suction gas passage H is enlarged, and also shortening a length of each suction gas passage H. Accordingly, even when the suction gas passage H is partly closed by a lace R of a thrust bearing, the flow path sectional area is prevented from decreasing, and a pressure loss can be prevented.</p> |
