Interior axial movement, offers air inlet and exhaust outlet on valve seat, internal piston is provided with air flue, and piston realizes valve seat when moving axially
Air inlet and exhaust outlet break-make, the first spring is provided between piston and valve seat, under free state the first spring make contact and
Piston has air inlet and exhaust outlet connection in the position away from still and moving plate on valve seat；
Still is fixed on valve seat, and moving plate can be moved axially in valve seat, and second spring is provided between moving plate and valve seat, from
By moving plate under state because the pressure of second spring is adjacent to still, closing of circuit；When contact receives external pressure, contact and piston to
Contract, have air inlet and the exhaust outlet on valve seat disconnects, and piston promotes moving plate to separate with still, and circuit disconnects.
Further, ejector pin is provided between the piston and moving plate, promotes moving plate to separate with still by ejector pin.
Further, gap is left between the piston and ejector pin, spring is provided between piston and ejector pin, piston is to contract
When, then first compression spring promotes ejector pin, ejector pin to promote moving plate to separate with still.
Further, it is provided with sealing gasket between the piston and valve seat axial direction.
Further, the piston has been disposed radially two seals ring with valve seat.
Air valve of the present utility model and pressure switch integrated morphology, including still, moving plate, contact, piston and valve seat；Touch
Head, piston, still and moving plate are installed in valve seat, and piston one end is connected with contact, the other end and rotor contact, contact and work
Plug can be moved axially in valve seat, and under free state, contact, piston rest on the leftmost side, moving plate in the presence of the first spring
Still is adjacent in the presence of second spring.In shelves, by ambient pressure to contract, piston is promoted for pile-up valve contact, piston
Moving plate is separated with still, and now air inlet disconnects with exhaust outlet, and circuit disconnects.
The utility model is integrated with pressure switch by gas path control valve.Can reduce by a neutral gear location hand feeling, effectively change
Kind shift-feel.A hole machined on manipulation device housing is reduced, shifting block or spline housing groove and raised processing is reduced, zero is reduced
Part processing, assembly cost.
