PURPOSE:To render the constituent parts of a hydraulic unit still simpler than ever before in form, by setting up a swivel cylindrical member in space made up between locking cylindrical members, while causing suction and discharge motions of fluid to be carried out with the turning motion of the swivel cylindrical member. CONSTITUTION:In process of turning a swivel cylindrical member 22 by (a) deg., an interspace between the outer wall surfce of one side end part of the swivel cylindrical member 22 and the inner wall surface of a casing 11 keeps in touch at a point P1 and there is produced a sealed space A while a clearance is produced between the outer wall surface of the other side end part of the swivel cylindrical member 22 and the inner wall surface of the casing 11, so that fluid inside the space A gets dischaging through this clearance and thereby volume of the space A decreases according to the motion of the swivel cylindrical member 22 while the taking-in of new fluid is started at the opposite side of the contact point P; thus the constituent parts of a hydraulic unit comes to be simple in form. |
