Five Way Cylinder Valve

In this air cylinder the functions of a working piston and a five-way valve are combined.

Within cylinder 2, with five ports A1, A2, B1, B2 and C, moves a double- landed piston 3. With piston 3 in its leftmost position, As is connected with B2 and B1 with C. When compressed air is admitted to port A1 and with port A2 vented the piston moves to the right. When piston 3 reaches its right hand position (as illustrated) B2 is connected with C and A1 with B1. Ports B1 and B2 can be connected to the ends of a second cylinder, or with atmospheric pressure air. By alternately directing compressed air to A1 and A2 and venting A2 and A1, the ends of the second cylinder are alternately subjected to high pressure. At the same time piston 3 can do some work. Serial operation of two cylinders is attained with a minimum of control valves.
