Abstract: PURPOSE:To restrain thermal affection to a scroll part and ensure airtight and pressure resisting properties by forming the scroll part, a tubular member and bottom body member of a case such that position to which the scroll part and tubular member of a case are fixed are deviated by a predetermined interval from positions to which the bottom body member and tubular member of the case are welded fixedly. CONSTITUTION:A scroll compressor 1 has a case formed of a lid body member 3 and bottom body member 4 respectively fitted in both upper and lower openings of a tubular member 2. A motor 6 as a driving means and a scroll part 16 driven by the motor to compress gas of refrigerant or the like are received in the case. The scroll part 16 is composed of a block 13, movable scroll member 20, shim plate 21 and fixed scroll member 22. Thus, positions to which the scroll part 16 and tubular member 2 are fixed are formed to be deviated by a predetermined gap from positions to which the bottom body member 4 and tubular member 2 are fixedly welded.

Abstract: PURPOSE:To obtain an axial swash plate type variable displacement pump which can simultaneously improve suction ability and reduce surface pressure between a cylinder block and a valve plate by adopting simple structure. CONSTITUTION:This pump is provided with a cylinder block 4 rotating together with a rotary shaft 3 and a valve plate 7 opposite to a cylinder block end face on a side opposite to a swash plate 6, and a circular suction port 70 and a discharge port 71 are separately and symmetrically formed near the center of the above valve plate 7. On the other hand, the cylinder block 4 is provided with an oblique oil path 41 extending from each cylinder hole bottom corner toward the domains of the suction port 70 and of the discharge port 71. In addition to that, each cylinder hole 40 of the cylinder block 4 is severally provided with an oil leading hole 42 which is drilled in parallel to the rotary shaft 3 apart from the oblique oil path 41 for leading pressure oil in the cylinder hole 40 toward the valve plate 7 on a side nearer to an outer diameter than the suction port 70 and the discharge port 71.
