A regulating valve comprising a housing having a cylindrical valve chamber, the valve chamber being provided with at least one inlet and at least two outlets, the inlet and the outlets being at least partially closeable as needed by a common valve body arranged in the valve chamber and rotatable around an axis, the valve body being operable by an actuator, the inlet and/or at least one of the outlets being surrounded by a sealing device on the side of the housing facing the valve body and the sealing device being able to be brought into sealing engagement with the valve body under elastic preload. The valve body is designed having the shape of the segment of a cylinder and is bounded on the peripheral side by two boundary surfaces which each have an edge on the side facing the housing, the edge overtravelling the inlet during its opening being designed as an efflux edge and having an elliptically shaped recess extending in axial direction. Configured in the valve body is a duct-shaped opening which extends between the boundary surfaces and penetrates them.

A heating module for a mixture-compressing combustion engine which is arranged between an induction pipe and a cylinder head of the combustion engine. The induction pipe, the heating module and the cylinder head delimit at least one intake port in which at least one electrically heatable heating element is arranged which constitutes a component of the heating module. The heating module is connectable with connecting terminals to an electric current source and the joining surfaces between the induction pipe, the heating module and the cylinder head are sealed by a sealing device. The heating module includes at least one thin plate made of metallic material. A conductor made of electrically conductive material is secured on the plate. The sealing devices are constructed in one piece with the heating module on the side facing the induction pipe and the side facing the cylinder head.

An elastic mounting apparatus for vibration-decoupled mounting of a turbocharger housing on an internal combustion engine. The mounting apparatus includes a clamping element with two spring elements arranged in a functionally serial relationship. The clamping element joins the housing and the internal combustion engine so as to allow relative vibration between the two. The first spring element includes an annular spring member made of elastomeric material and a second spring element formed by at least one disk spring. The clamping element is penetrated by a clamping screw, and the disk spring can be compressed by the clamping screw in such a way that its spring rate, after compression to the intended preload, is substantially zero. The housing is configured as a turbocharger housing with at least one intake pipe. The intake pipe is braced in a vibration-decoupled and sealing manner on the cylinder head of the internal combustion engine by a sealing element made of an elastomeric material. The clamping screw is threadable into the crankcase of the internal combustion engine. The disk spring includes a disk spring packet with at least four individual springs oriented opposite to one another.

A liquid separator for the separation of liquids from gases is disclosed. The separator has an inlet orifice for receiving a flow of the gas laden with liquid, a first outlet for the liquid and a second outlet for the gas liberated from the liquid, and an adjusting mechanism for varying the available cross-sectional area arranged in the inlet orifice. The inlet orifice has a tubular passage cross-section and is bounded along its entire length by a dimensionally fixed wall. The adjusting mechanism has a pressure control assembly having a pneumatically operable control element which is arranged within the inlet orifice in a manner allowing relative movement therewith.

A regulating valve, comprising a housing having a cylindrical valve chamber, is disclosed. The valve chamber is provided with at least one inflow and at least two outflow ports. The inflow and the outflow ports can be at least partly closed off as required by a single common valve body arranged in the valve chamber that can rotate about an axis. The valve body acts as a rotary valve and can be actuated by a drive. The inflow and/or at least one of the outflow ports is surrounded on the side of the housing facing the valve body by a seal. The seal can be brought into sealing engagement with the valve body under an elastic preload. The valve body has an extension in the peripheral direction of the valve chamber that is delimited in each case by an edge, such that the flowoff edge passing over the inflow port while it is opening has an axially extending elliptical indentation.

The clamping element joins the housing and the internal combustion engine another so as to allow relative vibration.

A second spring element is formed by at least one disk spring, such that the clamping element is penetrated by a clamping screw, and such that the disk spring can be compressed by the clamping screw in such a way that its spring rate, after compression to the intended preload, is substantially zero. The housing is configured as a turbocharger housing with at least one intake pipe, such that the intake pipe has at one end, on the side facing the cylinder head of the internal combustion engine, an intake pipe flange that is braced in a sealing and vibration-decoupled manner against the cylinder head by an annular sealing element made of elastomeric material.

A heating module for an internal combustion engine with external mixture formation and fuel injection and at least one intake port and one injection nozzle is disclosed. An electrically heatable heating element, which can be surrounded by flow on all sides, is arranged in the intake port, the heating element being capable of connection to an electrical power supply by means of terminals. The heating element is formed by a laminated composite part which has a trough-shaped cross section transverse to the direction of flow.

A louver for selectively closing flow openings defined therethrough comprising a stationary support grid including a plurality of equidistantly spaced, first rods extending in a first direction to define flow openings therebetween, a movable grid including a plurality of spaced, second rods extending parallel to the first rods and being movable relative to the first rods in a second direction perpendicular to the first direction from a first position in which each of the second rods at least partially overlaps a respective one of the first rods to a second position spaced from said first position by a distance approximately equal to the equidistant spacing between said first rods and a plurality of substantially impermeable, flexible, flat structures each having first and second longitudinal edges and each of which is connected along the entire length of its first edge to one of the first rods and along the entire length of its second edge to a respective second rod that at least partially overlaps said one first rod in the first position. The flat structures have a width that is at least as wide as the width of the equidistant spacing whereby when the second rods are moved to the second position the flat structures close the flow openings.

A sealing ring for sealing about a relatively-movable shaft has a sealing surface and resilient means for resiliently bearing the sealing surface on the shaft. At least one annular projection projects from the sealing surface for contacting the shaft. The annular projection is made recessional into the sealing surface, by making at least the portion of the sealing ring at the sealing surface of a rubber having a Shore A hardness of from about 65 to about 90, in such a way as to leave a portion of the sealing surface in contact with the shaft at an annular surface region spaced axially from the annular projection.
