ABSTRACT:
This invention discloses a linear programmer for controlling parts of a servo system by a fluid pressure. The programmer comprises a first body with a longitudinal bore. A second body is joined to the first body forming a manifold therebetween. Apertures in the first body provide fluid communication between the bore and manifold. A plunger is disposed so as to be longitudinally movable within the bore to connect and disconnect the manifold to a source of sub-atmospheric fluid pressure to thereby activate the parts of the system.
