valve group for a plant protection tyre braking then braking circuits.

摘要

the group valve includes two valves (v1, v2) between a junction of entry (1) intended to be connected to a compressor, and the two loops out (21.22) intended to be connected to the two circuit braking system braking.the outputs of these valves may be coupled to the inputs of the other two valves (v3, v4) through two valves (11, additional(2) opening pressure setting and lower than the opening pressure of the valves (v1 - v4).the second valves (v3, v4) are intended to be connected to a device for braking and exit ramp, respectively.pneumatic auxiliary devices of the plant of braking.
