Abstract: The present invention is a supplementary control valve device including a valve body, which may be reversibly displaced in a guide, in the direction of the longitudinal axis, between an opening solenoid and a closing solenoid. The magnetic yoke of the opening solenoid includes at least one extension, with direct contact with a web, connected to the guide on the end thereof facing away from the extension.

Abstract: The supplementary control valve device comprises a valve body, which may be reversibly displaced in a guide (3), in the direction of the longitudinal axis, between an opening solenoid (1) and a closing solenoid (2). The magnetic yoke (4) of the opening solenoid (1) comprises at least one extension (5), with direct contact with a web (6), connected to the guide (3) on the end thereof facing away from the extension (5).

Abstract: Disclosed is a subunit having a hollow cylinder which is provided with an opening on at least one face and in which a spring bearing is arranged on the inside of the face and a first valve spring resting against said spring bearing. A shaft that is guided within the spring bearing is disposed in the first valve spring so as to be reversibly movable in the direction of the longitudinal axis of the hollow cylinder. A thrust bearing for the first valve spring is located at the end of the shaft, which faces away from said face of the hollow cylinder, the thrust bearing being connected to the shaft. A second valve spring is placed between the thrust bearing and the interior on the opposite face of the hollow cylinder.

A second valve spring (6) is placed between the thrust bearing (5) and the interior on the opposite face (1a) of the hollow cylinder (1).

Abstract: The valve element is composed of a valve stem, at one of whose ends a valve head is arranged, said valve head being of concave design in the direction of the valve stem, having on the outside a continuous annular region and having at least two cutouts between the annular region and the central connection point for connecting to the valve stem which are closed off by at least one closure part.

Abstract: Electronic components are arranged outside of the cooling channel of a motor vehicle's engine.

Abstract: The present invention relates to an electric motor having a housing. The housing includes an internal chamber in which the rotor is mounted with its shaft in at least one bearing. An aim of the invention is to provide an electric motor whose housing includes an internal chamber, at least one part of which is sealed in a particularly reliable manner against the external chamber of the housing. To achieve this, one area of the housing has a stepped bore in which a seal is located, through which the shaft of the rotor projects out of the housing. The stepped bore has a first diameter with a first dimension and a second diameter with a second dimension, the first dimension being greater than the second dimension.

Abstract: In an electric motor having a rotor which is arranged in a rotationally fixed manner on a shaft (4), a fixed bearing (7) is prestressed axially against a stop (9) by a spring element (11) in order to bear the shaft (4). The spring element (11) has an annular shape and has a larger external diameter than the fixed bearing (7). A rim (13), which is produced by peening, of the bearing plate (5) engages behind the external circumference of the element (11).

Abstract: A gas pedal for a motor vehicle has a pedal arm which is mounted pivotably in a holding part and has a restoring device, which slides along the rear side of the pedal arm, and a damping element for damping the movement of the pedal arm. A setpoint generator generates, from the relative movement of the pedal arm with respect to the restoring device, electric signals which can be varied as a function of position.

Abstract: In an electric motor, one one bearing plate (4) is made of plastic. A heat dissipation plate (9) is arranged a short distance in front of that side of the bearing plate (4) which faces the interior of the electric motor. The heat dissipation plate (9) carries heat from a bearing (5) to an electric motor housing (6), which is made of metal. This allows the electric motor to be manufactured particularly cost-effectively.
