A device for contactless determination of a rotary angle has two bodies which are movable relative to one another, at least one sensor coil through which an alternating current flows and whose inductivity and alternating current resistance value changes due to a relative change of a size of regions of a first one of the bodies which regions are associated with the at least one coil and composed of a material selected from the group consisting of an electrically conductive material and ferromagnetic material, the first body being arranged with mechanical prestress relative to a second one of the bodies.

Device for determining rotary angle

The control apparatus has a fuel injection pump, into which suction chamber fuel is fed by a feed pump that aspirates from a tank. A reversing valve is included in the connecting lines between the tank and the fuel injection pump, and by means of this valve, to turn off the engine, the line connections can be changed such that the suction chamber communicates with the feed side of the feed pump and the compression side of the feed pump communicates with the tank. The reversing valve is embodied as a two-position multiposition valve and has an electromagnet, disposed, partly spray-coated, in the valve housing, which is of plastic, of the multiposition valve. A valve member can be displaced counter to the force of a restoring spring by the electromagnet; the valve member acts upon one ball at a time, serving as a closing body, of double seat valves disposed on both sides of the valve member. The balls are not connected to the valve member but instead are acted upon by it only upon adjustment of the valve member in one acted upon by the pressure of the fuel prevailing in the valve housing.

Control apparatus for turning off an internal combustion engine

A discharge system is proposed which serves to introduce volatilized fuel into an intake tube of an internal combustion engine. The discharge system includes a discharge regulation valve, which on one side is located at an outlet line of an absorber element that emits volatilized fuel and on the other side is located at an outflow line which leads to the intake tube downstream of a throttle device. The discharge regulation valve includes a bottom portion and a cover between which one end of a leaf spring is firmly fastened. The other end of the leaf spring is loosely guided in a gap between the bottom portion and the cover. An armature is joined to the leaf spring and a valve closing body is secured to the armature remote from the leaf spring. A core is secured on a magnet housing disposed in the bottom portion and has a through conduit, which at one end terminates at a valve seat. An electromagnetic coil is disposed in the magnet housing and is triggerable in a clocked manner by an electronic control unit in accordance with engine operating characteristics. The spacing between the valve seat and the valve closing body adjusts automatically in accordance with the pressure difference at the valve seat.

Discharge system for introducing volatilized fuel into an internal

To provide for reliably sealing conductors or cables into a plug connector housing, the plug connector housing is formed with bores (2) in each of which a sealing bushing or sleeve (5) is located surrounding the outer insulating jacket (3a) of the conductor or cable. To protect the seals and prevent distortion and damage to the seals upon bending of the cables, and end seating and retaining part is received in an end recess (9) of the housing . The end seating and retaining part, in accordance with the invention, is formed of two half elements (11, 12) which surround the cables (3) and extend through the recess (9) from the bores (2) towards the end of the housing. The two elements (11, 12), each, are retained in the housing by a projection-and-recess snap-in connection (21, 23; 22, 24), and the two elements permit easy assembly which can be automated for mass production. For two or more conductor plugs the recess is 'figure 8' or undulated shaped, and the two half-elements are 'half-figure 8' or undulated elements, each with semi-cylindrical recesses (17, 18) surrounding an associated conductor or cable, which extends inwardly into an individual bore (2) in the housing.
