Abstract

A multistage hydraulic integrated adder valve device 10, having an output 11 connected to a load is settable to various positions by a plurality of binary latch valves 12. The latch valves 12 are selectively operated by pneumatic actuated diaphragms 13. In certain applications, the diaphragm actuated valves 12 are driven from perforated tapes of a pneumatic tape reader 14 having pneumatic conduit connections 15 through connector block 16. For computer operation of the hydraulic integrated adder 10, a pneumatic converter 17 is provided. This converter comprises plural electro-pneumatic valves 18 having electrical input conductors 19 connected to a computer interface for receiving binary electric signals, which switch valves 18 to apply air through connector block 16 to the diaphragm actuated valves 12.

Electro Pneumatic Converter for Hydraulic Actuator

A multistage hydraulic integrated adder valve device 10, having an output 11 connected to a load is settable to various positions by a plurality of binary latch valves 12. The latch valves 12 are selectively operated by pneumatic actuated diaphragms 13. In certain applications, the diaphragm actuated valves 12 are driven from perforated tapes of a pneumatic tape reader 14 having pneumatic conduit connections 15 through connector block 16. For computer operation of the hydraulic integrated adder 10, a pneumatic converter 17 is provided. This converter comprises plural electro-pneumatic valves 18 having electrical input conductors 19 connected to a computer interface for receiving binary electric signals, which switch valves 18 to apply air through connector block 16 to the diaphragm actuated valves 12. The converter 17 consists, preferably, of commercially available pneumatic solenoid valves mounted to a common manifold plate which is mounted directly onto the connector block 16, thereby minimizing hose connections when the pneumatic tape reader connection 15 has been disconnected from connector block 16 for computer operation.
