An arrangement for protecting an electronic circuit is suggested which is mounted in a housing and is insulated relative to the housing. At least one connection is provided with which the electronic circuit is connected to a pregiven potential. A voltage-dependent resistor is introduced between the housing and the at least one connection for protecting against ESD-pulses and EMV-irradiation.

Device protecting an electronic circuit

The invention relates to a throttle device to be received in the intake system of an internal combustion engine, and includes a mechanism housing for receiving an actuator that actuates a throttle valve. A lid element which can be mounted on the mechanism housing is embodied in modular form and includes an opening for receiving a sensor module, which can be positioned independently of the mounting position of the lid element on the mechanism housing relative to a bearing point.

Throttle housing comprising a modular lid element

A method for producing a throttle valve unit, which is contained in a throttle device comprised of two housing halves. A receptacle housing for an adjusting drive mechanism that actuates the throttle valve unit is formed onto the throttle device. The throttle valve unit is produced in one piece in a single operation using an injection molding process in which a frame structure is produced, which encompasses a valve surface on both sides of a valve shaft that has bearing elements.

Method for producing a throttle valve unit with integrated throttle valve

The invention relates to a throttle device for the intake section of an internal combustion engine, wherein the throttle device has a multi-part housing that contains a throttle valve device in movable fashion, which can be actuated by means of an actuating drive unit. A base housing, which is embodied as an injection molded component and accommodates the throttle valve device, can also accommodate first housing parts of different flange patterns as interfaces with the intake section and additional second housing parts, which are accommodated so that they can move in relation to the base housing, in order to modify the air conduction.

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

The invention relates to a throttle device for controlling a fluid flow in an internal combustion engine, with a multi-part housing, whose first housing part and whose additional housing half rest against each other at contact surfaces and the fluid flow is controlled by means of a flat valve element, which can be adjusted in the flow conduit of the fluid flow by an actuating drive. The throttle device contains at least one sealing and compensation element, whose shaping of its inner wall defines the flow cross section of the fluid flow in the throttle device and which has a contact surface, which can seal cavities on its side oriented toward the housing.

Throttle devices housing with flexible compensation elements for internal combustion engines

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.

Device for repositioning a rotating element

A motor vehicle door lock with mechanical lock elements in a lock unit, with a lock mechanism, with several interacting elements in a control unit which is separated from the lock unit, optionally with lock electronics in the control unit , and the lock unit being arranged spatially separate from the control unit in or on a motor vehicle door or hatch, the lock unit being connected to the control unit by a remote power transmission, and the lock element in the lock unit, by the remote power transmission, is mechanically actuated from an element of the lock mechanism in the control unit. Reaching of the locked position or the main catch position of the lock latch is mechanically signaled to the control unit by the drawing function of the remote power transmission.
