End offers the exhaust entrance 303a connected with its inner cavity, offers the air exit connected with its inner cavity close to fixed plate one end
303b and air exit 303b and it is extraneous connect, exhaust entrance 303a and air exit 303b face are arranged, for the ease of will be left
The compressed gas of the right gas chamber 125 of gas chamber 124/ is expelled in exhaust valve 302, the exhaust entrance 303a and ipsilateral first
Opposing pipe 1, the inner cavity company of the input terminal of opposing pipe 1 and the first check valve 140 are provided between check valve 140
It connects and is located between the sealed cylinder 145 under ring-shaped step 144 and original state at the connection, opposing pipe 1
Output end connect connection with exhaust entrance 303a, in order to control the on-off between exhaust entrance 303a and air exit 303b, institute
It states exhaust plug 304 to be arranged to be axially parallel to the axial rod-like structure of reciprocating lever 123, exhaust plug 304 is along its axial end
Portion position, which is actively plugged in the interior intracavitary of exhaust valve 302 and constitutes sealed slide-and-guide with it, to be cooperated, 304 edge of exhaust plug
Docking docking under 304a and original state of rising as high as the banks is offered on the periphery of its axial end position rises as high as the banks 304a for connecing
Logical exhaust gas intake port 303a and air exit 303b.
More specifically, the exhaust plug 304 coaxial fixing sleeve along its axial medium position is equipped with external boss
304b, the external activity of exhaust plug 304 are socketed with reset spring 304c, and there are two reset spring 304c settings and difference position
In the side of external boss 304b, the one end reset spring 304c is contradicted with external boss 304b, the other end and exhaust valve 302 support
It touches and the elastic force of reset spring 304c is directed toward external boss 304b by exhaust valve 302 always, two reset bullet under original state
The elastic force of spring 304c mutually balances and is located at external boss 304b among two exhaust valves 302, keeps docking the 304a that rises as high as the banks
Exhaust entrance 303a and air exit 303b are connected, exhaust valve 302 is connected, by the bullet for overcoming reset spring 304c
Power effect slides 304 left/right of exhaust plug, makes to dock rise as high as the banks 304a and exhaust entrance 303a, air exit 303b mistake
It opens, exhaust valve 302 disconnects.
Gas inside the compressed right gas chamber 125 of left gas chamber 124/ is discharged a part first by exhaust valve 300, and
Closed state is switched to afterwards and the gas of remainder is expelled in alternately valve actuating mechanism 400 is used for alternately valve actuating mechanism
400 automatic trigger, therefore, it is necessary to the left end terminal/right end terminals for making active piston 122 slide into cylinder body 1 to make before
Exhaust valve 300 switches to closed state, for this purpose, the external boss 304b is fixedly installed close to one 121 one side of cylinder body
Length direction is parallel to the axial rectangular connecting panels 305a of reciprocating lever 123, the medium position of connecting plate 305a along its length with
External boss 304b is fixedly connected, and the one end of connecting plate 305b along its length is provided with to be extended to towards cylinder body 1
Trigger board 305b, the distance between two trigger board 305b are less than the distance of 122 side-to-side movement of active piston, the reciprocating lever 123
End position on be fixedly installed linkage rack 307, be fixedly installed on linkage rack 307 triggering convex block 308 and original state under
Triggering convex block 308 is located at the middle position of two trigger board 305b, pushes trigger board 305b left/right by triggering convex block 308
Movement drives the sliding of 304 left/right of exhaust plug, so that exhaust valve 300 be made to switch to closed state.
As the scheme that the present invention more optimizes, in order to avoid triggering convex block 308 causes damaged in collision to trigger board 305b,
Buffer Unit is provided on the trigger board 305b, Buffer Unit includes being arranged on trigger board 305b and being parallel to reciprocating lever
