An example actuator assembly includes a valve body having a body locating shoulder as a protrusion from an interior peripheral surface of the valve body, and an actuator having an end that is inserted into the valve body. The end has a first portion with a first diameter and a second portion with a second diameter that is larger than the first diameter, and the second portion includes a threaded region. A locating shoulder is between the first portion and the second portion of the end of the actuator arranged at a position where the first diameter changes to the second diameter. The locating shoulder mates with the body locating shoulder of the valve body when the actuator is inserted and screwed into the valve body to enable alignment of the valve body and the actuator.

A motor vehicle quick coupling for a fluid connection in a motor vehicle includes a coupling body in which a fluid line is formed through which a fluid can flow. The quick coupling has a first fluid interface which is designed such that the quick coupling can be connected directly to a fluid-conducting component of the motor vehicle, in particular to a radiator, such that the component supports the quick coupling. The quick coupling has a second fluid interface which is fluidically connected to the first fluid interface via the fluid line. The quick coupling includes a valve which has a valve closure element that extends into the fluid line.

An improved mechanical dump valve for a liquid level control system. The dump valve comprises a splined shaft that communicates with the valve actuator by a toothed member, such as a splined bore in a dump valve hub. The dump valve also may include pressure ports. Still further, the present invention includes a liquid level control system comprising a trunnion assembly and a mechanical dump valve in which the trim motion of the float valve is transmitted by means of splined shafts in both the trunnion assembly and the dump valve assembly. The inventive system may comprise float weights for weighting the float accurately without having to drill the float and load it with sand or other weighting material. Also included is a kit for retrofitting existing liquid level control systems that use D-shaped connections with splined components.

To suppress increase of a pressure loss in a channel and blocking of the channel due to water adhering to a rectification mesh provided downstream of a butterfly valve. A fuel cell system includes: a butterfly valve provided on a pipe between a fuel cell and another component; and a rectification mesh provided on a downstream side of gas flowing in the pipe relative to the butterfly valve, a mesh that rectifies a flow of the gas being formed in the rectification mesh. The rectification mesh has, in its lower end part in a vertical direction, a first opening part in which the mesh is not formed.
