Abstract
PURPOSE: To synchronize two change-over valves precisely, by connecting a branch pipe, which opens to the outside through an orifice, to the passage which connects the discharge port of each change-over valve with a monitor.
CONSTITUTION: A supply pipe P from the pressure fluid supply source is connected to intake ports of a valve 1 and valve 1', and a work pipe A, which is connected to the press, to discharge ports of the valve 1 and valve 1'. A monitor 2, which has a piston 2a, that is maintained in neutral position being pushed by springs from both ends, and a microswitch 2b, that detects the movement of the piston 2a, has its one end connected by piping 3 to the work pipe A at the location where the work pipe A is connected to the discharge port of the valve 1. A branch pipe 6 used for discharge which has an orifice 5 is connected to this pipe 3.
