摘要： A fuel pump unit (1) for dispensing fuel comprises a fuel container (2), a fuel conduit (4) connected to the fuel container (2), and a metering means (11) which is arranged in the conduit (4) to measure a flow of fuel therethrough. The metering means (11) comprises a first metering unit (14) to measure the flow of fuel within a first flow range, and a second metering unit (12) to measure the flow of fuel within a second flow range. The first flow range comprises larger flows of fluid than the second flow range.

摘要： A slide valve has a cylindrical valve housing (1) with at least one opening (2) and a turnable slide (3, 5) for closing and uncovering the opening (2). The valve slide, whose sealing surface is congruent with the valve housing, comprises a body (3) and a sleeve (5) made of a yieldable material and movably arranged on the outside of the body. The outside of the sleeve is made of a material with good sealing properties. The friction between the sleeve (5) and the valve housing (1) is normally higher than the friction between the body (3) and the sleeve (5), such that, as the slide (3) is turned, the body slides inside the sleeve (5) and the sleeve (5) rolls on the inside of the valve housing (1). In this valve, a good sealing is obtained without necessitating great force for operating the slide (3) and without the outside of the sleeve being improperly worn. The principle may also be applied to other valve configurations than a cylindrical valve housing and a turnable slide.
