Abstract: A multi-port thermal module which includes a central housing, a plurality of flow cavities integrally formed as part of the central housing, at least one inner housing connected to a first side of the central housing, a first plurality of inner flow channels integrally formed as part of the first inner housing, each of the first plurality of inner flow channels in fluid communication with at least one of the flow cavities, and a first outer housing connected to the first inner housing. A portion of each of a first plurality of flow channels is integrally formed as part of the first inner housing, and another portion of each of the first plurality of flow channels is integrally formed as part of the first outer housing. A rotor located in the central housing is rotated to various orientations to direct fluid between the plurality of flow cavities.

Abstract: A seal arrangement for use in a fluid control valve includes: a first seal configured to sealingly abut against an actuatable valve body of the fluid control valve; a second seal configured to sealingly abut against a valve housing of the fluid control valve; and an elastically deformable intermediate spacer, arranged between the first seal and the second seal and configured to elastically space the first and second seals apart. At least in an installed state of the seal arrangement in the fluid control valve, the first seal and the second seal are joined to one another in positively locking fashion in an axial direction of the seal arrangement.

Abstract: The inventive method provides that during a first step, a circular, discoidal pre-molding is produced from a first plastic by injection molding. After the pre-molding is hardened, a ring made of a second plastic is subsequently placed, by injection molding, on the pre-molding while encircling the narrow side of the pre-molding and is hardened as well. The invention also relates to an application of the method.

Abstract: A drive device (10, 100) with an actuating drive (40, 130) for driving a movable element (11, 110), in which drive device a lever (62, 144) coupled to the movable element (11, 110) is capable of being driven by the actuating drive (40, 130) via a gear (48, 132), the lever (62, 144) being capable of being acted upon by a firmly supported return spring (34, 164) so as to be capable of being pivoted back into a basic position (82, 161), and, in the basic position (82, 161), a first lever arm (64, 146) of the lever (62, 144) being acted upon by a stop (84, 160), is to have a particularly low space requirement and at the same time absorb momentum energy of the gear (48, 132) in a particularly reliable way in the event of a failure of the actuating drive (40, 130).

Abstract: The invention relates to a method for producing a housing (12) for a throttle valve connection piece (10), which housing is to have particularly high dimensional stability. For this purpose, the housing (12), which has a throttle orifice (16) for a throttle valve (20), is produced from plastic (14) by the injection molding method, plastic (14) being partially injected around a metal cylinder (28) which, at least in the region of the throttle valve (20), forms the throttle orifice (16). In this case, before the injection molding method, an expanding mandrel (50) is expanded against the inner face (33) of the metal cylinder (28). During the injection molding method, the inner face (33) of the metal cylinder (28) is supported at least partially by the expanding mandrel (50). After the injection molding method, a reduction in the outer circumference (80) of the expanding mandrel (50) is carried out in order to remove the expanding mandrel (50) from the interior (70) of the metal cylinder (28).

Abstract: A throttle valve body (10, 100), especially for an internal combustion engine of a motor vehicle, having a tubular body (16, 116), which comprises at least an outer casing (16A, 116A), an inner casing (16B, 116B), a first end face (16C, 116C) and a second end face (16D, 116D), the inner casing (16B, 116B) of the tubular body (16, 116) forming a flow duct (20, 120) through which a gaseous medium (56, 156), especially air, can flow in a main flow direction (58, 158), a throttle plate (24, 124) swivel-mounted on a throttle shaft (22, 122) being arranged in the flow duct (20, 120), is to have an especially low weight and be manufactured at least partially from standard components. For this purpose the outer casing (16A, 116A) of the tubular housing (16, 116) is at least partially enclosed by a housing (12, 112) made of plastic (14, 114), at least one actuator (30, 130) for the throttle shaft (22, 122) being arranged in the housing (12, 112) and the tubular body (16, 116) being largely composed of metal (18, 118).

Abstract: A load adjustment device for an actuating member which determines the power of an internal combustion engine has a rotatably mounted stop lever (10) on a setting shaft (2). A torsion spring (13) is tensioned between said stop lever (10) and the setting shaft (2). A stop arm (14) of the stop lever (10) engages between an emergency-travel stop (11) and a minimum-load stop (15). For the swinging of the stop lever (10), there is provided a driver (12) which is arranged on an intermediate gear wheel (7) and drives a setting part (3) of the setting shaft (2), which part is developed as toothed segment.
