<p>PURPOSE:To stabilize the balance of compression and rotation by supporting a pair of rocking plates having a piston connected thereto, rockably back and forth and rotatably relatively together with the drive plate, by a pair of rotating drive plates rockable back and forth. CONSTITUTION:A pair of rotating drive plates 14, which are slidable to the axial direction and can rock back and forth with fulcrum at a shaft center, are provided on a drive shaft 7 located in a crank room C by way of sleeves 20, 20 in such a manner as they are respectively disposed with a space. And a pair of rocking plates 12, 12 connected to pistons 9 through connecting rods 11 are removably supported by the drive plates 14, 14 in such a manner as they can rock back and forth and can be simultaneously rotated relatively together with the drive plates 14, 14. In addition, a control valve 28 is provided onto either of housings 3, 6 so as to control the pressure in suction chambers S1 and S2 of a front and a rear housings 3 and 6, which are connected to either of the outer end surface of cylinder blocks 1 and 4, or the pressure in the crank room C.</p> |
