ABSTRACT:
A two stage vacuum break or fluid motor device of the type used to control choke valves of internal combustion engine carburetors. The motor uses a single diaphragm in which the fluid motor plunger operates in a first stage in response to movement of a portion of the diaphragm and in a second stage in response to movement of the entire diaphragm. The stages of movement are under the control of separate sources of manifold pressure which may be made available to the device independently of each other. The two stages of operation may be used to control one or more choke valves through a single output plunger or to control a pair of output plungers movable independently of each other.
