Abstract
Disclosed is a check valve (5) that is screwed into a threaded bore (1) of a housing (2) of a hydraulic subassembly between a first pressure side (26) and a second pressure side (27) by means of an external thread (11) which is disposed in a first cylinder section (8) of a cylindrical valve housing (6) of the check valve (5). A passage duct (39) which allows a hydraulic fluid to flow between the sidewall of the threaded bore (1) and a first removed portion (16) of the surface area (10) of the cylindrical valve housing (6) is embodied in at least one angular segment (a1, a2, and a3) of the valve housing (6).
Claims17
Hydraulic assembly, situated in the housing of which are a continuation bore embodying a first pressure side, a threaded bore embodying a second pressure side, and between the first pressure side and the second pressure side, a nonreturn valve having an external thread which is formed on a first cylindrical portion of a cylindrical valve housing and can be screwed into the threaded bore,
- a passage duct for a hydraulic fluid flow being formed, between a side wall of the threaded bore and a first region of material removal of the lateral surface of the cylindrical valve housing, in a plurality of angular segments (α1, α2, α3 and α4) of the valve housing,
- wherein the first regions of material removal are continued in a second cylindrical portion adjoining the first cylindrical portion and serve, with a plurality of second regions of material removal situated between the first regions of material removal exclusively in the second cylindrical portion, as engagements for a tool for screwing the nonreturn valve into the threaded bore.
