PROBLEM TO BE SOLVED: To secure a pushing force against a fixed scroll by means of a movable scroll.SOLUTION: A plate 24 has a communication hole 24a which can intermittently communicate a back pressure region with a suction pressure region, by moving a position of a protrusion part 23e by an orbiting motion of a movable scroll 23. Therefore, only when the back pressure region communicates with the suction pressure region through the communication hole 24a during the movement of the position of the protrusion part 23e by the orbiting motion of the movable scroll 23, a pressure of the back pressure region is decreased. When the back pressure region does not communicate with the suction pressure region through the communication hole 24a, the pressure of the back pressure region is not decreased.

177	Screw compressor	JP2011214251	2011-09-29	JP4911260B1	2012-04-04	モハモドアンワーホセイン; 広道上野; 貴司井上; 正典増田; 晃松岡
A screw compressor (1) includes a slide valve (60) for changing a compression ratio. A valve body (65) of the slide valve (60) includes a sealing projection (66) extending along a rear end surface (74) thereof. In a slide valve housings (31) of a casing (10), the sealing projection (66) separates a low-pressure space (S1) and a high-pressure space (S2) from each other when being in slidable contact with a slidable-contact curved surface (32) of the casing (10). A refrigerant pressure in the low-pressure space (S1) is always applied on the entire nonslidable-contact surface (77) in the valve body (65). Thus, a force that pushes the valve body (65) toward a screw rotor (40) is constant, independently of the position of the slide valve (60), thereby decreasing a change of a clearance between a front surface (71) of the valve body (65) and the screw rotor (40).

A motor vehicle vacuum pump includes a pump chamber with a pump rotor, an outlet chamber, a separating wall which separates the pump chamber from the outlet chamber, and an outlet valve arranged in the separating wall. The outlet valve is designed so that a compressed gas escapes from the pump chamber into the outlet chamber therethrough. The outlet valve is formed by a valve opening in the separating wall, a valve seat having a raised shape arranged around the valve opening, and a leaf spring as a valve body. The leaf spring abuts on the valve seat in a closed position and is spaced from the valve seat in an open position. The leaf spring has a radial overlap with the valve seat in the closed position of less than 1.5 mm and a radial projection outward beyond the raised valve seat which is larger than 1.0 mm.
