Embodiment Construction

[0018] FIG. 1 shows a first embodiment variant of a flow control valve 1 a according to the invention. The figure shows a machine housing 2 with a pressure medium channel 3 formed in the form of a deep bore, into which a pressure medium channel 4 also opens transversely. The flow control valve 1a is seated in the channel 3 by means of a longitudinal force fit between the cylindrical housing surface 5 of the valve housing 6 and the diametrically widened opening 7 of the pressure medium channel 3 in such a way that: On the side facing away from the opening 7 , a first pressure medium connection 8 is connected to the pressure medium channel 3 , while a second medium connection 9 extending radially through the housing shell surface 5 is connected to the further pressure medium channel 4 . The end 10 of the valve housing 6 facing the opening 7 and adjacent to the second medium connection 9 has a closed housing bottom 11 and is hydraulically sealed to the pressure medium channel 4 b...

Abstract

The invention relates to a flow-control valve (1 a, 1 b) for throttling a hydraulic pressure medium. Said flow-control valve (1 a, 1 b) is mounted with an outer envelope surface (5) of a valve housing (6) in a pressure medium channel (3) of a machine housing (2) comprising a plug (12) which is sealed from the pressure medium, on the mouth (7) of the pressure medium channel (3), close to the machine housing (2), and comprises a first pressure medium connection (8) on a side opposing the mouth (7). The plug (12) is formed by the flow-control valve (1 a, 1 b), a second pressure medium connection (9) extending radially through the outer envelope surface (5) and being connected to another pressure medium channel (4) which transversally merges into the original pressure medium channel (3).; An end section (10) of the valve housing (6), facing the mouth (7), comprises a closed housing bottom (11) and is inserted into the pressure medium channel (3) by means of a hydraulically sealing longitudinal press fit.

Description

technical field [0001] The invention relates to a flow control valve with a throttle cross-section for throttling a hydraulic pressure medium, in particular in a lubricant circuit of an internal combustion engine. The flow control valve is mounted via the substantially cylindrical outer surface of the valve housing in the pressure medium channel of the machine housing at the opening of the pressure medium channel into the periphery of the machine housing A pressure-medium-tight sealing plug is provided, and the flow control valve has a first pressure-medium connection connected to the pressure-medium channel on the side remote from the opening. Background technique [0002] Flow control valves of this type are known as throttling devices in hydraulic systems and hydraulic control systems and are intended to supply a hydraulic medium under pressure with a reduced volume flow to a hydraulic load. In the field of internal combustion engines, flow control valves of this type ca...
