Abstract: A pressure relief cover for reducing pressure generated in a cell-like cavity, such as a battery cell, having a cover part which holds a seal for sealing a housing opening up to a predetermined cell pressure and having a holding device to fasten it to the housing opening. An advantageous type of mounting with a reliable function is achieved in that the holding device has a spring clip attached to the underside of the cover part at the housing opening with a plurality of radially outwardly directed spring tongues which at their ends are provided with spring sections which are resiliently movable backward in the radial direction upon pressing the cover part onto the housing opening through the opening edge and snap back under a wall area around the opening edge after penetrating the housing opening.

Abstract: A pressure relief valve for reducing pressure arising in a cell-like cavity, such as a battery cell, including a cover which has a seal for sealing a housing opening up to a predetermined cell pressure and is provided with a holding device in order to hold said cover on the housing opening, the holding device having a spring clip which is attached to the lower face of the cover that faces the housing opening and has a plurality of radially outwardly directed spring tongues which, at the ends thereof, are provided with spring portions which, when the cover is pressed onto the housing opening, can be moved back resiliently in the radial direction through the opening edge and, after passing through the housing opening, snap back under a wall region around the opening edge, wherein a bearing device, which is separate from the cover prior to mounting and to which the spring clip is fixed by a support part, is connected to the cover on the lower face thereof that faces the housing opening, a connection adapter bein

Abstract: A method for producing a clamping ring in which pins that protrude in the region of or near a ring contour are formed on the top and bottom surfaces of a flat sheet metal material and after the ring contour is cut out, burrs that are produced during the cutting are removed by a deburring process. Advantages for the machining of the clamping ring are achieved if before a finish cutting by a complete cutting-out of the ring contour that is carried out from the one side of the flat sheet metal material, the ring contour is partially cut out from the other side in the vicinity of or near the pin protruding from this other side.

Abstract: A snap ring which has a substantially radially directed ring section with a support surface and a substantially axially directed ring section with a lateral surface, the two ring sections forming an L-shaped cross-section, and a ring gap. For ease of use, at least one of the two end sections that face each other in the ring gap is turned outward in the radial direction in relation to the rest of the ring profile by bending, and, in the bent region, the axial ring section has a notch.

Abstract: A screw with anti-loosening means, which includes a securing element with a ring portion and that can be inserted about a shaft of the screw under a head thereof and, with the screw in a state in which it is screwed on a base, prevents the screw from being turned back counter to a screwing-in direction. The securing element has on the ring portion, on a side facing the surface of the base, at least one projection which can be pressed into the surface when screwing in the screw. The securing element can have an outer circumferential region of the ring portion, with finger-like extensions which, with the securing element in the inserted state, extend along the circumference of the head and under spring-elastic forces of the securing element, contact a surface structure of the body that has an inhibiting action counter to the screwing-in direction.
