Problems solved by technology

However, this technique has the disadvantage that if a single part fails, the entire subassembly has to be replaced as a whole
Prone to misalignment and longitudinal play when assembling this subassembly to another
Said assembly is relatively complex due to the fact that it is carried out directly on the internal combustion engine (assembly)

Embodiment Construction

[0019] figure 1 Shown are a first subcomponent 10 and a second subcomponent 12 in a refrigerant circuit (not shown in detail) of a cooling system of an internal combustion engine. As shown, subassembly 10 is a thermostatic valve. The subassembly 10 is secured to the omitted engine section by a flange. The subassembly 10 is tightly secured by flanges 14 to the omitted engine section. As shown, the sub-component 12 is a cooling water regulator equipped with a stub 16 allowing connection to a rotary drive. The two subcomponents 10 and 12 should be connected to each other as a flow connection. This (fluid) connection should be effective when the subassembly 10 is fastened to the internal combustion engine. The subcomponent 10 comprises a pipe section 18 into which a pipe section 20 of the subcomponent 12 can be inserted. The design of the subcomponents will be clarified below. A resilient shank 22 integral with the subassembly 12 extends over, spaced from, and parallel to th...

Abstract

A coolant circuit includes a first pipe segment, a second pipe segment, and a seal between the pipe segments which are displaceable relative to each other. A resilient locking tang runs parallel to the first pipe segment and has a detent element. An elongated guide portion runs parallel to and is spaced from the locking tang between the pipe segment and the locking tang. Spaced-apart arms run parallel to the second pipe segment beyond the end of this second pipe segment. An axially parallel web is configured between the arms and is fitted at its end facing the second sub-assembly with a detent shoulder which is engaged from behind by the resilient detent element when the pipe segments are plugged into each other. The resilient tang is received at a closed fit between the arms, and the elongated guide portion is guided by the arms.

Description

technical field [0001] The present invention relates to a cooling system for an internal combustion engine as stated in claim 1 . Background technique [0002] It is known to design cooling water regulators for cooling systems of internal combustion engines, which have two subcomponents, one of which includes, for example, a temperature control valve. It is also known that the housings of such subcomponents, which are mostly made of plastic, are produced in one piece. However, this technique has the disadvantage that if a single part fails, the entire subassembly has to be replaced as a whole. This disadvantage wastes material and requires fine workmanship. [0003] It is also known that the aforementioned subcomponents are manufactured separately. Usually one of the subassemblies, the thermostat subassembly, is rigidly coupled to the internal combustion engine. Misalignment and longitudinal play are prone to occur when assembling this subassembly to another. Said assem...
