Patent ID: 7562860

Claim:
A hand-operated pressure regulating valve for compressed air guns, the pressure regulating valve comprising: a longitudinal axis; a pressure regulating unit having a cylindrical basic body with a centrally disposed nozzle passage piece, said basic body having one side being closed by a latching element in the form of a segment of a circle and another side with a spring pin and a compression spring; a basic valve body having an outer surface area, an axially and centrally disposed continuous nozzle passage with a cross section, a transverse bore, an external thread for screwing the pressure regulating valve into a mouth of any compressed air gun, and an internal thread for receiving a nozzle body, said axial and central continuous nozzle passage to be bridged and continuously closed within said transverse bore by said nozzle passage piece of said pressure regulating unit projecting from said transverse bore on both sides; said latching element and said spring pin lying opposite one another and projecting radially moveably from said transverse bore transversely to said longitudinal axis of the pressure-regulating valve and being directed toward said outer surface area of said basic valve body; a manually operable actuating ring having a securing ring for holding said pressure regulating unit in said transverse bore of said basic valve body transversely and in a functionally reliable way, said actuating ring having an inner surface area, approximately up to half of said inner surface area of said actuating ring having an eccentric shape in axial direction with a stop and with a plurality of shallow wells being concave, semicircular, equally deep and integrally formed therein; said actuating ring being manually rotatable in a horizontal plane around said basic valve body for latching said spring pin into said shallow wells on one side with said latching element touching said eccentric surface area on an opposite side, causing said latching element to compress or relax said compression spring in different parts of said eccentric surface area and said pressure regulating unit and said nozzle passage piece to be transversely displaceable relative to said nozzle passage, for reducing and increasing said cross section of said nozzle passage in vicinity of said transverse bore, within ranges determinable in terms of number and size; and in an installed state, said spring pin of said pressure regulating unit projecting through said compression spring seated in place out of said basic body and said transverse bore for radial movement transversely relative to said longitudinal axis and, by rotation of said actuating ring, latching in succession into said plurality of shallow wells.
