<p>PROBLEM TO BE SOLVED: To allow to retain a sufficient amount of lubricating oil in a crank chamber. SOLUTION: A drive shaft 11 inserted into a center bore 8 of a cylinder block 6 is rotatably supported by the cylinder block 6 through a radial bearing while a swash plate 20 connected to the drive shaft 11 is synchronously rotated in a crank chamber 10, and a piston reciprocates in a cylinder bore 7 following the rotation of the swash plate 20. A cylinder head is provided on an end surface of the cylinder block 6 through a valve plate and has an intake chamber 27 and a discharge chamber 28 for fluid, and the intake chamber 27 is communicated with the crank chamber 10 through the center bore 8, and a lubricating oil separator 31 rotated so as to synchronize with the drive shaft 11 is mounted to the drive shaft 11 extended into the crank chamber 10 with opposing to the center bore 8 of the cylinder block 6 forming a communicating passage between the crank chamber 10 and the intake chamber 27.</p> |
