Abstract: A fuel level indicator is mounted on a casing (2) in a fuel tank (1) and includes a float lever (6) connected to a lever arm (17), the float lever (6) having an elbow portion (16) passing through an opening (18) in lever arm (17) and projecting into a hole (15) in a holder (9) for rotation therein. At its lower edge (19) the lever arm (17) engages a collar (20) of holder (9) and at its upper edge (21) the lever arm (17) engages a collar (22) of holder (9). In this way, the lever arm (17), and thereby float lever (6), is guided radially and axially on the holder (9). The float lever (6) is releasably secured to the lever arm (17) by resilient snap tabs (23). Accordingly, precise support of the float lever is obtained with a simple construction and with easy assembly and disassembly of the float lever.

Abstract: A pressure control valve having a valve body 2 consisting of metal material and a spring 10 determining the control pressure of the valve and designed as a flat pressure spring with radial arms, the spring being arranged in a chamber 20 of valve body 2 which is connected to the ambient atmosphere or to the inlet of the internal combustion engine. The flat pressure spring 10 is placed under tension between a deformable bead 12 of valve body 2 and a membrane cap 11 and the tension force of the spring is adjusted by deforming the bead 12.

Abstract: A separation for showers, bathtubs, or the like, including: a stationary, closed frame, made of several frame parts, for guiding at least one movable door element, and, if appropriate, for fastening a stationary door element; the at least one movable door element being suspended by rollers on the upper frame part of the frame; a seal for sealing the closed separation against discharging splashed or sprayed water; a closed lower frame part of the stationary frame, this lower frame part having a box-like cross section, an upwardly directed narrowed portion of predetermined height and width, and an inclined run-off surface adjoining one side of the narrowed portion; and a movable door element, the lower frame part of which faces the mentioned frame part of the stationary frame, and is provided with a downwardly open recess which conforms to the narrowed portion of the stationary frame part.
