Abstract
A rotational speed responsive type fluid pressure signal control valve comprises a plurality of fly weights rotated by a drive shaft, a sleeve operated by the fly weights, fluid passages provided in the valve and valve bodies actuated by the sleeve so as to open and close the fluid passages, thereby getting a fluid pressure signal from the fluid passages.
Claims1
A rotational speed responsive type fluid pressure signal control valve comprising, a drive shaft for transmitting rotating force, fly weights connected with said drive shaft, means combined with said fly weights for reciprocating according to the rotation of said fly weights including a push rod member for operating a valve body means, fluid passage means connected to a vacuum pressure source, actuators and atmospheric area, and valve body means associated with said fluid passage means for operation by said push rod member and said reciprocating means for opening and closing said fluid passage means according to the operation of said reciprocating means to provide a fluid pressure signal including a first valve body member associated with said push rod member to connect said actuators with said atmospheric area and a second valve body member comprising a dished spring valve thereby providing hysteresis of valve operation and for cutting off connection between said vacuum pressure source and said actuators.
