<p>PURPOSE:To increase oil retention by providing, at cylinder head, oil collecting chamber which is connected to oil collector formed by connecting a chamber between two cylinder bores at the lower part of cylinder block and swash plate chamber. CONSTITUTION:The chamber 11b between cylinder bores 10c, 10b of cylinder blocks 7a, 7b is connected with swash plate chamber to form oil collector 12. Also at the lower part of cylinder heads 9a, 9b, oil collecting chamber 23 is formed by oil collector separating rib 22. Furthermore, holes 18 are made in valve plates 8a, 8b to connect oil collector 12 and oil collecting chamber 23. By doing so, oil retention can be increased as much as the volume of oil collecting chamber 23.</p> |
