Abstract: Disclosed is a G-rotor pump in which a lid and a bottom of a pump housing are made of plastic. A spacer that supports the bottom is produced as a single piece with the lid, whereby the G-rotor pump can be embodied in a particularly inexpensive manner.

Abstract: The invention relates to a fuel pump (3) that is mounted in a fuel tank (1) of a motor vehicle. Said pump has a preliminary phase (6) and a principal phase (7), which are driven by an electromotor (5). The principal phase (7) lies directly in front of a flow pipe (17) to the internal combustion engine. The fuel that is transported by the principal phase (7) is taken in from a component (2, 21), into which the fuel of the preliminary phase (6) has been transported. As the principal phase (7) is located downstream of the electromotor (5), an impermissible heating of said electromotor is prevented. The fuel pump (3) also allows the starting times of the internal combustion engine to be extremely short.

Abstract: In a tire valve (10) for the rim (Q) of a pneumatic tire on a vehicle having a valve body (12) which includes a longitudinal bore (16) and which comprises rigid, in particular metal material with a valve base (20) which is arranged at one end and which has an annular shoulder (24) projecting radially from the valve body (12), the valve body (12) is connected at a spacing to a coaxial valve sleeve (48) by an intermediate tube (44) of elastic material and the valve sleeve (48) can be inclined limitedly with respect to the longitudinal axis (A) of the tire valve (10). The valve sleeve is to comprise rigid material—in particular a metal material—; the intermediate tube (44) bears clampingly at one end against a hollow shank (28) of the valve body (12) and at the other end surrounds the end region of the valve sleeve (48), which is in adjacent relationship at a spacing (u).

Abstract: An impeller for a feed pump designed, in particular, as a side channel pump or as a peripheral pump has two disk parts connected fixedly in terms of rotation to one another. The disk parts can be manufactured in simply constructed molds, for example by the injection molding method, and can be provided with virtually any desired geometries of guide vanes. The impeller has high stability due to the rotationally fixed connection between the disk parts.

Abstract: The invention relates to a fuel delivery unit for use in fuel tanks of vehicles, having a pump with a housing (2) and at least one outlet opening (3) arranged laterally thereon, having a reservoir (1) which can be filled with fuel and into which the pump can be inserted with little lateral installation space and from whose filling volume fuel is delivered to the outlet opening (3), and a line (15), in particular a rising line, which can be connected to the outlet opening (3), wherein at least the one line (15) can be connected to the outlet opening (3) by means of a releasable, pressure-sealed plug-in connection (S), it being possible for the outlet flow to be deflected in the region of the plug-in connection (S) by means of an elbow (6a).

Abstract: In an apparatus for measuring the tire pressure in a pneumatic tire of a vehicle by means of a measurement value sensor, which is acted upon by the tire pressure, on the rim bed (12) of a rim (10), which accommodates a tire valve (20), for the pneumatic tire, connected to the tire valve (20) is a signal housing (44) which is associated with the rim bed (12) and which includes an electronic sender means as the measurement value sensor for the tire pressure. The signal housing (44) is connected to the tire valve (20) by a hollow screw (40) which engages into the valve bore (28) and is adjustable relative thereto in such a way that the tire valve/signal housing combination can be used for equipping different rim cross-sections. That purpose is also served by base elements (52) which project from the underneath surface of the signal housing (44) and which sit on the rim bed (12) and which with the suspension point on the screw (40) form a multi-point mounting configuration.
