A fluid measuring or fluid control device has a housing the housing parts of which are fastened to each other by at least one screwed connection, in which a screw engages through an opening in a peripheral wall of the first housing part and is screwed into a threaded opening in the second housing part. An elastic seal is arranged between the housing parts. The first housing part has a first resting face, and the second housing part has a second resting face which are both in peripherally circumferential contact with the seal. The screw shank and an edge of the opening have cooperating frustoconical surfaces which are oriented such that the second housing part is displaced in the direction towards the first housing part when the screw is screwed into the threaded opening, the resting faces coming into contact with the seal.

Fluid measuring or fluid control device

A closed-loop control valve module for closed-loop controlling a fluid flow is described, which comprises an electrical valve actuator motor, wherein a valve spindle comprising a frustoconical sealing section is displaceable by means of the valve actuator motor along a valve spindle axis and the frustoconical sealing section, depending on the position of the valve spindle, releases or separates off a flow channel connecting a fluid inlet and a fluid outlet. A pressure compensation channel is provided which, at least in the closed state of the closed-loop control valve module, connects an end of the valve spindle opposite the valve actuator motor to a pressure compensation area or the fluid inlet in terms of flow.

Closed-loop control valve module

A solenoid valve has a housing, which has a fluid inlet and a fluid outlet, and an electromagnetic drive, which comprises a solenoid with a fixed core and a movable armature, wherein the armature interacts with a valve seat. A pressure compensation chamber which is bordered by a membrane is formed in the armature, wherein the pressure compensation chamber is in fluid connection in terms of flow with the fluid inlet by means of a pressure compensation channel.
