Abstract
A variable differential adjustor for a fluid pressure-actuated switch, with the fluid, in the preferred form of the invention, being air. The restrictor has a restrictor housing having a passage through which a pressure source has a portion which passes on its way to a pressure-actuated switch. A restrictor is provided for engaging the portion of the pressure source passing through the restrictor housing and is adjustable to variably alter fluid flow through the pressure source portion. The restrictor comprises a screw-like plug in the pressure source portion which is acted upon by a tube throttle to variably alter the passageway past the plug. A gauge may be provided for determining adjustment of fluid flow.
