The tension of spring and move to left, high pressure gas enters right control chamber after entering the 4th control pipe, on the other hand, the gas of left control chamber row
Go out, since spool both ends are there are pressure difference, spool, bowl valve move to left.
When the mutual switching for realizing compressor two stages of compression and twin-tub compact model in Fig. 1 and Fig. 2 by four-way valve, pneumatically
Guiding valve realizes the switching of four-way and two-way.
And the action of the solenoid directional control valve of four-way is by high in left control chamber, right control chamber in coil control air slide
The switching for pressing side gas and low-pressure side gas, to push spool to move left and right, with compressor two stages of compression and twin-tub compact model.
Universal solenoid directional control valve high side gas is connected to the 4th pipeline of air slide by the 4th connecting tube 400 currently on the market,
Low-pressure side gas is connected to the second pipe of air slide by third connecting tube 300.
It is existing when twin-tub compact model in the 5th connecting tube 500 when twin-tub compact model switches two stages of compression pattern
The gas of pressure at expulsion can pass sequentially through the first pipe of air slide, bowl valve, second pipe and pour third connecting tube 300, this
When third connecting tube 300 will appear the discharge pressure state of a period of time, that is, the air slide that third connecting tube 300 is connected to
The first pipe of air slide that is connected to the 4th connecting tube 400 of second pipe in be filled with same pressure condition, to
It is equal when can cause the air pressures of two control chambers of solenoid directional control valve at one end in the time, cause electromagnetic switch valve events different
Often, the problem of causing to switch.
