Abstract: The invention proposes a device for measuring the mass of a flowing medium, in particular the mass of air aspirated by internal combustion engines. The device has a platelike sensor element which is accommodated in a recess of a sensor carrier, and which with a sensor region that has at least one measuring resistor is exposed to the flowing medium in order to measure its mass. The sensor element is accommodated essentially flush in the recess and is retained in the recess by being glued to a bottom face in the recess. The bottom face of the recess of the sensor carrier has a troughlike indentation, which extends at least partially along the circumference of the sensor element outside the sensor region that has the at least one measuring resistor. The device according to the invention is intended to measure the mass of a flowing medium, in particular for measuring the mass of air aspirated by internal combustion engines.

Abstract: A multiway connector comprising a support part and a cover part including plugs. The plugs with the first electrically conducting contact elements and electrical conductors are arranged on the support part. The two-part construction of the multiway connector permits a problem-free mounting of the electrical conductors in the vicinity of a support part front face, for example, in guide grooves of the support part. The construction of the multiway connector is particularly suitable for the joint electrical contacting of electrically operable fuel injection valves.

Abstract: A fuel distributor for fuel injection systems of internal combustion engines has a distributor housing having a plurality of location holes, connected to each other by a fuel supply line, for accommodating electromagnetically actuated fuel injection valves, a hold-down firmly clamped on the distributor housing, for fixing the fuel injection valves in the location holes, and fixing means for fixing the distributor housing to the intake manifold of the internal combustion engine. For the noise decoupling of the fuel distributor from the adjacent add-on pieces, a noise-decoupling flat gasket is placed between the distributor housing and the hold-down on the one hand and the fixing means are formed by rubber-metal elements on the other hand.

Abstract: A fuel injection device for internal combustion engines has a fuel distributor which bears a plurality of connection pieces with radially projecting locking elements, and has a plurality of fuel injection valves, which are designed as so-called top-feed valves and are inserted fluid-tightly into the connection pieces. Provided to hold the fuel injection valves in the axial direction and to secure the fuel injection valves against rotation in the circumferential direction there is in each case a connecting member which engages in a circumferential groove in the valve casing and engages over the locking elements. In addition, the connection member has a fixing element which engages positively, at least in the circumferential direction, around a shaped element which is provided on the valve casing at a defined position.

Abstract: A multipin plug including plug housings which are connected in a floatingly movable manner in the horizontal and vertical direction to one central floor part of a receiving opening of the multipin plug so that offsets occurring between the first and the second electrically conductive contacting elements are compensated and damage is avoided. Such a multipin plug is particularly suitable for electrically connecting fuel injection valves to the multipin plug.

Abstract: A fuel injection device for internal combustion engines having a fuel distributor which bears a multiplicity of connecting pieces with radially protruding locking collars and a multiplicity of fuel injection valves constructed as so-called top-feed valves, said fuel injection valves being inserted liquid-tightly into the connecting piece. For the purpose of fixing each of the fuel injection valves in the axial direction as well as for securing the fuel injection valves against rotation in the circumferential direction, in each case a connecting element is provided which engages in an annular groove in the valve housing and engages over the locking collar. In addition, the connecting element has two fixing elements which engage in a positive-locking manner around, in each case, one of the molded elements at least in the circumferential direction, said molded elements being mounted in a defined position on the valve housing and on the connecting piece.

Abstract: A positioning apparatus including a positioner, a restoring suspension means, a servo drive and an actuator, the position of which determines the power of a driving engine. The restoring suspension means assures that the actuator is always in a precisely definable position regardless of any other spring. The restoring suspension means may include a plurality of integrally cohering restoring springs. Satisfactory operation of the apparatus is assured even if one of the restoring springs should fail. The servo drive is embodied such that in the event of an electrical defect the engine operates at an intended speed (rpm). The apparatus is particularly suitable for motor vehicles in which the engine rpm is to be regulated precisely in idling via a throttle valve.

Abstract: In a peripheral fuel-conveying pump, in which the rotatable impeller, provided with a plurality of vanes spaced from each other by grooves, is enclosed with the housing of the pump so that a fuel-feeding passage is formed between the inner wall of the housing and the periphery of the impeller. The dimensions of the fuel-feeding passage are defined by the first geometric characteristic R.sub.m which is a ratio between S and L, wherein S is the cross-sectional area of the space enclosed between the housing wall, defining the feeding passage, and the periphery of the impeller, and L is the length of the periphery of the portion of the impeller inserted into the fuel-feeding passage. R.sub.m must be in the range of 0.4-2 mm. The dimensions of the fuel-feeding passage are also limited by the second geometric characteristic R.sub.s =B/E and the third geometric characteristic RA=B/E, which must be in the range of 0.5-1.

Abstract: In known devices, the fuel injection valves, disposed in individual receiving bores, are retained individually with clamping shoes, and electrical contact is provided by individual electric plugs. The novel device is intended to assure that all the fuel injection valves are retained and provided with electrical contact simultaneously. The fuel injection valves inserted into receiving bores of a basic body are retained in common in the receiving bores by means of a contact-making outlet strip, slipped onto the basic body, and are electrically connected in common by means of electrically conductive contact elements. The entire compact device can be fastened as a unit to the engine and electrically connected, via a connection plug to an electronic control unit for trigging the fuel injection valves. The device makes adaptation to various engine types possible.
