PURPOSE:To reduce the number of parts, simplify assembly process and improve reliability by providing a static cylinder member which has a cylindrical surface concentric with a casing inside wall face of the captioned hydraulic device in united one body with a crankshaft. CONSTITUTION:A turning cylinder member 2 is housed in a housing formed by blocking both end faces of a cylindrical casing 1 with end plates 7, 8. The turning cylinder member 2 including a turning cylinder 61, which is cylindrical with a bottom and an opening end of which is blocked by means of a side plate 6, is formed by inserting, in a slot 63 provided on one side of the turning cylinder 61, a partition plate 4 fixed to the casing 1 and provided with a suction port 45 and a discharge port 46. Then, an expected volumetric hydraulic device is obtained through housing a static cylinder member 55, united in one body with a crankshaft 5, in the turning cylinder member 2 and making said member 2 support front and rear crank parts 53, 54 of the crankshaft 5 through bearings 12, 14. |
