ABSTRACT:
A solid state timing circuit exhibiting very high reliability under adverse environmental operational conditions such as are encountered in automatic truck lubrication systems. The circuit utilizes an electrochemical timing device operating in plate and deplate modes to achieve a periodic actuation of an inductive load. Two transistor stages are operatively associated with the electrochemical timing device and an R-C timing network is used to control one of these transistor stages.
