Problems solved by technology

But with the axial slots so arranged, failure of the pressure equalization holes is not prevented
[0005] In the known constructions, the corresponding disadvantage is that the deposition of pollutants in the communication bore or in the space behind the regulating body cannot be reliably reduced
As a result, the pressure balance function and the normal functionality of the regulatory bodies are threatened

Embodiment Construction

[0023] figure 1 The coolant valve shown includes a housing, and the housing 10 is designed to have a flow housing 12 and an actuator housing 16, the flow housing 12 with a flow channel 14 designed therein. And the actuator housing 16 arranged in which the electromagnetic actuator 18 is fixed to the flow housing 12.

[0024] The electromagnetic actuator 18 has an electromagnetic circuit, the electromagnetic circuit comprising: a coil 20, a coil 20 that can be powered by a plug 24, a magnetized core 26, a baffle element 28, a yoke 30, and a movable Armature 32. When the coil 20 is powered, the armature 32 is moved in the direction of the generated magnetic force along the core portion 26 in a known manner.

[0025] By coupling the armature 32 and the adjustment body 34 by the coupling member 36, the moving unit 35 is formed from the armature 32 and the adjustment body 34, and the coupling member 36 is designed as a one-piece and extended to the armature 32. The bore is fixed to the...

Abstract

Motor vehicles coolant valves are known that comprise a housing (10) which has an inlet (42) and an outlet (44), a flow cross-section which is formed between the inlet (42) and the outlet (44) and is surrounded by a valve seat (40), a control body (34) which can be placed on the valve seat (40) and which can be lifted from the valve seat (40), through-openings (62) in the control body (34), via which the inlet (42) is constantly connected to a chamber (52) on the control body (34) side facing away from the inlet (42), and an electromagnetic actuator (18) with an armature (32) which is coupled to and can be moved together with the control body (34). The aim of the invention is to maintain the functionality of the coolant valve for as long of a duration as possible even when dirt is present in the coolant. According to the invention, this is achieved in that at least one dirt pocket (64) is formed in the control body (34), said pocket having a closed base (65) which faces the inlet (42) and being open towards the chamber (52) formed on the control body (34) side facing away from the inlet (42).

Description

Technical field [0001] The present invention relates to a coolant valve for a motor vehicle having a housing having an inlet and an outlet; a circulation cross section, the flow cross section being designed in the inlet and the outlet. The valve seat is surrounded by the valve seat; the adjustment body can be lowered to the valve seat and can rise from the valve seat; a plurality of communication openings in the adjustment body, the inlet through the communication opening The space communicates with the adjusted body on the side of the inlet; an electromagnetic actuator with an armature, the armature coupled to the conditioned body and can be moved. Background technique [0002] In particular, a pressure balance valve is known in the air of the air, wherein the switching time can be reduced by the pressure balance. For example, it referred to herein is an air commutation valve for a turbocharger in a motor vehicle. Such air commutation valves are described, for example, in DE 10 ...
