Three=way two=way valve - has impulse operated selector member connecting two outlets to inlet alternately

摘要

The 3-2 way valve is for a pneumatic or hydraulic control system, particularly for pneumatic doors, having a housing with an inlet and two outlets and containing a selector member movable between two positions. A first mechanism opens the passage between the inlet and the first outlet in the first position of the member, and that between the inlet and the second outlet in the second position, shutting off the connection to the other outlet in each case. A second impulse-operated mechanism changes the member over between the two positions.
