20080283010 | CAM SHAFT PHASE SETTER AND VACUUM PUMP FOR AN INTERNAL COMBUSTION ENGINE - A device for adjusting the phase position of a cam shaft of an internal combustion engine and for supplying an assembly with a partial vacuum, said device comprising: a phase setter for adjusting the phase position of the cam shaft relative to a crankshaft of the internal combustion engine; a vacuum pump for the assembly; and an attachment housing for the vacuum pump, wherein the attachment housing is mounted on the internal combustion engine and forms a housing or at least a housing cover for the phase setter. | 11-20-2008 |
20120060683 | VACUUM PUMP WITH VENTILATING MEANS - A vacuum pump for supplying a machine assembly with a negative pressure includes a housing and a housing cover surrounding a delivery chamber. The delivery chamber includes a low-pressure region having a working inlet connected to the assembly, and a high-pressure region having a working outlet. A delivery member moveable within the delivery chamber, which, when moved, suctions air into the delivery chamber through the working inlet and expel it at an increased pressure through the working outlet. An outlet valve is arranged at or downstream or the working outlet and at least makes it difficult for air to flow back into the delivery chamber. The delivery chamber is connected to the external environment of the vacuum pump via a ventilating connection in order to establish at least partial pressure equalization with the external environment when the delivery member is stopped and a negative pressure prevails in the delivery chamber. | 03-15-2012 |
20120145100 | DEVICE FOR ADJUSTING THE ROTATIONAL ANGULAR POSITION OF A CAM SHAFT - A device for adjusting the rotational angular position of a cam shaft relative to a crankshaft of a combustion engine includes a supply branch for supplying pressure fluid to setting chambers to generate torque acting on a rotor; and a pressure storage device arranged in the supply branch and including a spring and a storage chamber which can be filled with the pressure fluid against a spring force of the spring, wherein the storage chamber begins to fill, against the spring force, at a start-of-filling pressure which is at most as large as a hot idling pressure which the pressure fluid exhibits when the combustion engine is idling in its hot operational state, and continues to be filled against the spring force if the hot idling pressure is exceeded. | 06-14-2012 |

20090143152 | COUNTER TRACK JOINT WITH BALL CAGE - A constant velocity joint in the form of a counter-track joint. The circumferential length (L | 06-04-2009 |
20100311509 | CLEARANCE-FREE CONSTANT VELOCITY UNIVERSAL JOINT - A constant velocity universal joint is disclosed that comprises an outer joint part, an inner joint part, torque transmitting balls, an annular ball cage, and a supporting mechanism. The outer joint part includes circumferentially distributed outer ball tracks. The inner joint part includes circumferentially distributed inner ball tracks. The torque transmitting balls are guided in pairs of tracks, wherein each track includes an outer ball track and an inner ball track. When the joint is in the aligned condition, the pairs of tracks, at least in a central joint plane, widen in coinciding axial directions. The annular ball cage is defined by a cage axis. The cage is positioned between the outer joint part and the inner joint part and comprises circumferentially distributed windows in which the torque transmitting balls are held with a clearance. The ball cage comprises an axial clearance relative to the outer joint part. The supporting resiliently supports the ball cage relative to the outer joint part and acts on the ball cage in the direction opposed to the direction in which the pairs of tracks widen. The supporting mechanism comprises a carrier element connected to the ball cage and a separate supporting member, wherein the supporting member is resiliently supported on the carrier element and rests against the outer joint part. | 12-09-2010 |
