Patent DE-4213803-A1 (DE)
Inventor: FEIGEL HANS-JOERG DIPL ING
IPC: B60G17/08
Filed: 1992-04-27
Abstract: In order to reduce both the overall length and the manufacturing costs of a pilot operated, two stage valve for running gear regulating systems, the pilot body (14) is ring-shaped so that the medium flows off in the radial direction, and the valve body (22) is designed as a spring mounted plate (28).

Title: Safety locking device for vehicle covers
Inventor: SCHRADER JUERGEN DIPL ING
IPC: E05B83/16
Filed: 1993-04-26
Abstract: The invention relates to a safety locking device for vehicle covers, especially for front bonnets of motor vehicles, with a rotary-latch fastener, the fastener parts of which are arranged on the body and on the cover, with the result that, during the closing of the cover, the forked rotary latch of one fastener part cooperates, by engaging around it, with a fastener shackle of the other fastener part and is held in its locking position by a blocking member engaging on it, with a spring loading of the forked rotary latch in the opening direction of rotation, by which the forked rotary latch is driven after the disengagement of the blocking member, and with a safety device, by means of which, after the disengagement of the blocking member, the fastener shackle remains coupled to the fastener part supporting the rotary latch and is released completely only after a safety lever engaging over it has pivoted away. In order to allow an engagement of the rotary latch with a high locking safety, the forked rotary latch can be unlocked in two stages, in such a way that, as a result of the first unlocking operation, it snaps into an intermediate position, in which its forked leg engaging over the fastener shackle acts as a safety lever, and that, triggered by the second unlocking operation, it snaps into its release position.
