Title: Fuse link in vacuum housing - forms part of plug connector for medium voltage installations with short link generating small amount of heat
Inventor: SILBERMANN ERICH ING GRAD
IPC: H01H37/76
Filed: 1978-05-24
Abstract: The vacuum fuse (2) has a fusible element (2d) with electrodes (2b, 2c) contained in a housing (2a). The housing is extended to form a collar (2h) shaped to fit the mating flanges (1c, 1d) of the halves of the insulated shrouding of the medium voltage connector (1). The collar flanges serve to locate both fuse and connector halves. The vacuum fuse has a very short element (2d) thus it generates very little heat in normal operation. After fusing the insulation resistance of the fuse is very high thus eliminating the need for a backup circuit breaker.

Patent DE-2909248-A1 (DE)
Inventor: NAGEL GUENTHER ING GRAD
IPC: F04B1/12
Filed: 1979-03-09
Abstract: The working piston is supported via a fixed piston shoe (11) on a piston-guiding surface (12). For the purpose of pressure distribution, the piston shoe on its outer side has a relief pocket (16) which communicates with the cylinder chamber (8). To this end, there is provided on the outer side of the piston shoe (11) a recess (19), inserted in which there is a separate gasket (14) which can move within narrow limits and is provided with the pocket (16). Between the rear of said gasket and the base plane of the recess a gap (24) is formed which communicates with the cylinder chamber (8) via the duct (15). The areal extent of said gap is limited by a seal ring (25) running in an annular groove. The relief pocket (16) proper is accessed only by a duct (45) from the area of the seal ring (25). The internal diameter of the gap is sized in such a way that the gap acts as an initial restrictor. This design of the piston shoe relief ensures a close fit against the piston-guiding surface, virtually friction-free sliding with little leakage oil even in the event of any manufacturing imprecisions of the piston-guiding surface. <IMAGE>
