Abstract

A control unit for use in the engine compartment or in the transmission of a motor vehicle. The control unit has a line section for an engine or transmission fluid, a circuit carrier, and a base plate. The base body is mounted on the base plate. The circuit carrier is arranged between the base body and the base plate. The base body has a plurality of parallel channels each having a respective outlet. At least one of the plurality of parallel channels forms a portion of the line section. A separate cover is mounted on the base body, the cover having a single inlet coupled to the plurality of parallel channels. The cover is, other than only the inlet, connected to the base body in a fluid-tight manner, and the inlet is the only fluid passage through the cover.

Claims

1. A control unit for use in the engine compartment or in the transmission of a motor vehicle comprising:

a line section for an engine or transmission fluid;

a circuit carrier;

a base plate;

a base body mounted on the base plate, whereby the circuit carrier is arranged between the base body and the base plate, and the base body comprises a plurality of parallel channels each having a respective outlet, at least one of the plurality of parallel channels forming a portion of the line section; and

a separate cover mounted on the base body, the cover having a single inlet coupled to the plurality of parallel channels,

wherein the cover is, other than only the inlet, directly connected to the base body in a fluid-tight manner by at least one of welding, caulking, or screwing the cover to the base body, and the inlet is the only fluid passage through the cover.

2. A control unit according to claim 1, wherein the base plate and/or the cover are made of aluminum, casting, or plastic material.
