Abstract

An internal combustion engine drives a reciprocating compressor installed with various flow control valves in a gas pipeline. A pneumatic system using logic elements and control boards controls the starting, running and stopping of the engine and compressor and the working of the valves either from a point at the site or from a remote point. There are several choices of the relative amount of control by an attendant or automatically and including automatic imposition of load and response to variations in load and also automatic response to anomalous or dangerous conditions.

Claims (4)

1. An automatic control system for an engine driving a gas compressor having a compression pocket and adapted to be connected in a pipeline comprising means for isolating said pocket from the remaining compression volume of said compressor, a step-by-step programmer, means for generating pneumatic pulses, means responsive to a control factor for regulating said pulse generating means, means responsive to said pulses for stepping and positioning said programmer, and pnuematic means responsive to the position of said programmer for operating said pocket isolating means, and means for controlling the operation of said engine, and pneumatic means responsive to the position of said programmer for operating said engine controlling means.
2. An automatic control system for an engine driving a gas compressor having a compression pocket and adapted to be connected in a pipeline comprising means for isolating said pocket from the remaining compression volume of said compressor, a step-by-step programmer, means for generating pneumatic pulses, means responsive to a control factor for regulating said pulse generating means, means responsive to said pulses for stepping and positioning said programmer, and pneumatic means responsive to the position of said programmer for operating said pocket isolating means, and means substantially responsive to the brake mean effective pressure of said engine, and pneumatic means contrOlled by said brake mean effective pressure responsive means for stepping said programmer to control said engine.
3. An automatic control system for an engine driving a gas compressor having a compression pocket and adapted to be connected in a pipeline comprising means for isolating said pocket from the remaining compression volume of said compressor, a step-by-step programmer, means for generating pneumatic pulses, means responsive to a control factor for regulating said pulse generating means, means responsive to said pulses for stepping and positioning said programmer, and pneumatic means responsive to the position of said programmer for operating said pocket isolating means, and a pneumatically actuated vibration shut-down device responsive to excessive engine vibration, and means controlled by said programmer for temporarily disabling said vibration shut-down device.
4. An automatic control system for an engine driven gas compressor and including a pneumatic control board incorporating a pneumatic duct extending between an entrance port and an exit port, a pneumatic means for stopping said engine, means connecting said exit port to said pneumatic means, a pneumatically actuated engine shut-down device responsive to an operating factor of said engine, means connecting said shut-down device to actuate said stopping means, and means controlled by said engine shut-down device for venting to atmosphere the supply of pneumatic fluid at said entrance port.
