Patent number: 7726625Abstract: A transfer device for transferring an actuator displacement, has a housing with a first recess having a first and second plunger displaceably mounted. These plungers are actively connected via at least one transfer chamber by a fluid. The active connection causes the second plunger to be displaced when the first plunger is moved and vice versa. The transfer chamber is hydraulically coupled via a sealing gap to a compensating chamber compensating the pressure differences, in a delayed manner. The transfer device also has a chamber device with a compensating chamber, a chamber housing, and a first plunger. The chamber device has a device with a first body with a recess including a second body, and with an elastomer placed in the recess between the first and second body. The elastomer has a first groove extending at least partially along the recess.Type: GrantFiled: December 6, 2004Date of Patent: June 1, 2010Assignees: Continental Automotive GmbH, Carl Freudenberg KGInventors: Hans-Peter Arnold, Patrick Delp, Hellmut Freudenberg, Achim Löll, Willibald Schürz, Martin Simmet, Günter Ziegler, Hanspeter Zink

Patent number: 7673811Abstract: A compensating element (30) for an injection valve has a cup-shaped body (32) with a cup base (34) and a recess. Furthermore, the compensating element has a piston (36) which makes a clearance fit in respect of the recess of the cup-shaped body (32) on an axially extending guide segment (41) of the piston (36) and which is arranged at least partially axially moveable with the guide segment (41) in the recess of the cup-shaped body (32). A sealing element (44) is arranged on the side of the guide segment (41) facing away from the cup base (32) and couples the cup-shaped body (32) with the piston (36). A hydraulically and/or pneumatically sealed system is delimited by the cup-shaped body (32), the piston (36) and the sealing element (44). The coupling of the sealing element (44) with the cup-shaped body (32) and/or the piston (36) is friction-fit.Type: GrantFiled: June 5, 2006Date of Patent: March 9, 2010Assignee: Siemens AktiengesellschaftInventors: Stefan Schuster, Willibald Schürz, Martin Simmet, Hanspeter Zink

Patent number: 7100895Abstract: Disclosed is a travel-transmitting element for an injection valve, comprising a pressure-loaded storage chamber which is filled with a hydraulic fluid and a storage element that is provided with an elastomeric bellows-type member. In order to ensure sufficient steadiness of the rotational speed over the service life, the inventive elastomeric bellows-type member is provided with a stiffening element which ensures constant radial stiffness over the service life at least in some sections thereof.Type: GrantFiled: December 9, 2004Date of Patent: September 5, 2006Assignee: Siemens AktiengesellschaftInventors: Willibald Schürz, Martin Simmet, Hanspeter Zink

Patent number: 7017346Abstract: A device for transmitting a displacement of an actuator to a setting element comprises two pistons that delimit two transmission chambers and a compensation chamber with a housing. The compensation chamber is hydraulically connected to the two transmission chambers. The transmission chambers transmit a displacement of the first piston in order to effect a displacement of the second piston. The compensation chamber serves as a reservoir for the transmission medium with which the transmission chambers are filled. The compensation chamber is delimited by an elastomer ring. The elastomer ring depicts a simple and economical realization with which it is possible to subject the compensation chamber to the action of pressure and to change the volume of the compensation chamber at the same time. In a preferred embodiment, the elastomer ring is externally subjected to the action of a tension force via a pressure ring.Type: GrantFiled: January 13, 2005Date of Patent: March 28, 2006Assignee: Siemens AktiengesellschaftInventors: Willibald Schürz, Martin Simmet, Hanspeter Zink
