Abstract: A pressure regulator comprising a housing having an inlet port and an outlet port, a linearly sliding member for selectively covering a section of a passage between the inlet port and the outlet port, a diaphragm interconnected to the linearly sliding member to slide the linearly sliding member in reaction to pressure levels in the housing, and a valve seat located in the passage between the inlet port and the outlet port. The linearly sliding member includes a sealing disc for preventing fluid flow past the valve seat. The valve seat is located closer to the outlet port than to the inlet port.

Abstract: A turn lock bezel mounts an instrument gauge on an instrument panel by exerting axial retention forces that force a bezel ring against a front margin of a mounting aperture in the instrument panel and a dial graphic and dial plate of the gauge against a rear edge of a retaining ring that holds a window glass in the bezel ring and passes axially into the mounting aperture. In a first embodiment, when the bezel is turned a small acute angle in one direction, it can be extracted from the mounting aperture leaving the gauge behind in the instrument panel, and when turned a small acute angle further, the bezel can still be extracted, but it now extracts the gauge too. In a second embodiment, a lost motion connection is provided between the bezel and the gauge so that finger tip clearance will exist between the rear edge of the bezel ring and the instrument panel before the bezel begins to extract the gauge.
