Embodiment Construction

[0020] It can be seen from FIG. 1 that the pressure sensor or pressure switch 10 is inserted into a housing 12 , which is formed, for example, as an injection-molded part. The pressure sensor or pressure switch 10 is preferably inserted into a cavity 14 enclosed by the walls of the housing 12 . On the housing 12 of the pressure sensor or pressure switch 10 there is a plug connector 16 likewise formed by injection moulding, by means of which the signal of the pressure sensor or pressure switch 10 can be transmitted to an evaluation or control unit. Inside the housing 12 of the pressure sensor or pressure switch 10 there is a first connecting piece 18 , to which a pressure accumulator, for example a brake booster of a vehicle brake system, can be connected. In this embodiment, the housing 12 of the pressure sensor 10 and the first connecting piece 18 are a single component. On this component there is a second connecting piece 28 for connecting a pressure source for charging the...

Abstract

The sensor (10) has a connection port (18) running in a housing (12), and a return valve (32) integrated in the housing. Another connection port (28) is provided for a pressure source, and the return valve is arranged between flow section areas (24, 50). The return valve includes a valve body (34, 38), which is centered with a central hole (46) of a perforated disk (42) or a wall formed in one of the connection ports. The housing includes a cavity (14), whose base is formed by a mantle surface of one of the connection ports.

Description

technical field [0001] The invention relates to a pressure sensor for detecting an overpressure or underpressure, in particular at a pressure accumulator, having a housing in which a first connecting piece extends. Background technique [0002] A plug connection for a medium-carrying line is known from DE 102 40 130.6-16. The plug-in body comprises at least one connecting point, wherein the sleeve-shaped body made of a first material is positively received on a plug-in body with an elastically formed web, movable in a fixing direction and in a release direction. superior. If piezoelectric actuators are used in fuel injection systems, which are used, for example, to actuate fuel injectors of compression ignition internal combustion engines, it may be necessary to maintain a residual pressure of several bar in the fuel return system of such internal combustion engines. In the fuel return systems used hitherto, whether in external combustion engines or compression ignition en...
