A throttle device, includes a housing, a gas conduit, a throttle shaft, a throttle body movable by means of the throttle shaft. According to the invention, a bearing is provided for supporting the throttle shaft on the housing, in which for sealing off an interstice in fluid-tight fashion between the throttle shaft and the housing, and in particular outside the bearing, a viscous medium is disposed in the interstice.

Throttle device

A final control element movable between a minimal and a maximal position for controlling an internal combustion engine is acted upon by a first spring element acting in the closing direction and a second spring element acting in the opening direction, the latter having a first end and a second end. The first end of the second spring element is supported in stationary fashion in a housing. The second spring element transmits its intrinsic tension in the tangential and radial directions either to a bearing point on the final control element or to a second bearing point of the housing and is adjustable in its angular position by means of an adjustable stop.

Final control element for controlling internal combustion engines

An electric-motor adjusting unit for a metering system of an internal combustion engine, having an adjuster housing and an adjusting shaft rotatable therein that actuates a final control element, having a commutator motor coupled to the adjusting shaft, having a sensor for detecting the rotary position of the adjusting shaft, and having a carrier plate that can be secured in the adjuster housing, on which plate on the one hand a brush holder for the commutator motor and on the other a plug electrically connected to the brush holder and to the sensor are disposed, in order to obtain a prefabricatable assembly unit with which installation tolerances in the adjuster housing can be compensated for, the sensor being disposed on a carrier, and on the carrier and on the carrier plate, joining means corresponding with one another for joining the carrier and the carrier plate are embodied.

In a device for restoring a rotary member to a defined basic position, having a three-dimensionally fixed fixation cam that predetermines the basic position and having a slaving cam, which is coupled with the rotary member and is movable past the fixation cam, of which cams, each has one stop face each on sides facing away from one another, and having a clamp spring, which embraces the cams with prestressing by way of two bent-away spring legs, in order to achieve a freedom of play in rotation between the spring legs and the cams in the basic position, at least one spring leg is countersunk, with at least one leg segment, in at least one of the cams so far that in the basic position, with a leg segment fitting over the other cam, it rests without play on the stop face of the other cam.

Device for restoring a rotary member

A throttle device in the intake section of an internal combustion engine; the throttle device including a housing part, which contains a flow cross section for an air flow. In the housing part, bearing points are provided for a throttle valve device, which can be actuated by means of an actuating drive. The actuating drive can be inserted into a receiving housing, which has first and second guide surfaces that permit the installation of the actuating drive. Fastening means are provided on the circumference surface of the receiving housing and can accommodate a closing and contacting element, which contacts electrical contacts of the actuating drive.

Throttle valve unit with drive unit receptacle and drive unit contact

A device for restoring a rotary member into a defined normal position, with a spatially stationary fixed catch, which predetermines the normal position, and a driver catch, which is coupled to the rotary member and can be moved past the fixed catch, each of which has stop surfaces embodied on each of its opposing sides, and with a clamping spring, which encompasses the catches in a prestressed fashion with two bent spring legs, in order to prevent a rotary play between the clamping spring and the catches in the normal position, and an elastic spring element in at least one leg section of the spring legs extending across the stop surfaces of the catches, which spring element is supported against the associated stop surface with a spring force that is less powerful than the prestressing force of the clamping spring.
