The pump head for an american and french valve

摘要

The present invention relates to a pump head for an american and french valve, which comprises: a housing (10), which has a receiving space (111) and a through hole (121); a lever (20), with the housing (11) is connected in an articulated manner; a piston (30), which in the receiving space (111) of the housing (10) is arranged and a receiving hole (31) and on both sides in each case a hole (33); two clamping units (50), which in each case contain a clamping piece (51), which in the hole (33) of the piston (30) is arranged and a slanted surface (511); a positioning element (60), which in the receiving space (111) of the housing (10) is arranged; a coupling element (70) extending between the piston (30) and the positioning element (60) is situated, and a sloping guide surface (713); and a plunger unit (80), which in the receiving hole (31) of the piston (30) is arranged, wherein, when during inflating by an american valve (92) of the lever (20) of the release position into the printing position is rotated, the piston (30) of the lever (20) is moved downward, as a result of which the coupling element (70) is moved along with it and presses the positioning element (60), which thus is deformed and the american valve (92) clamps, wherein the inclined surfaces (511) of the clamping elements on the inclined guide surface (713) of the coupling element (70), as a result of the clamping pieces (51) of the release position is to be pushed into the clamping position and thus the plunger unit (80) terminals.
