초록 ▼

A low profile fluid powered actuator particularly for valves of the type in which the valve element is rotated to open and close the flow passageway through the valve body, the actuator having a novel internal porting system, means for direct attachment of the valve stem to the shaft of the actuator

대표청구항 ▼

A fluid powered actuator comprising: a housing having a cylindrical piston passageway therethrough and a shaft bore therein, said shaft bore being transverse to and intersecting said piston passageway; a shaft rotatably mounted in said shaft bore and extending through said piston passageway, said shaft having a longitudinal rod receiving bore extending into at least one end of said shaft, and said rod receiving bore having wrench surfaces therein; a pinion fixedly attached to said shaft within said piston passageway; a pair of pistons tightly disposed in said piston passageway on axially opposite sides of said pinion and movable in said piston passageway toward and away from said pinion, each of said pistons having an integral piston skirt extending axially from said piston along said piston passageway toward said pinion, said piston skirts being radially opposite each other in said piston passageway, each having a gear rack operatively engaging said pinion; first means for providing fluid communication from the exterior of said housing to the interior of said piston passageway between said pistons; second means for providing fluid communication from the exterior of said housing to the ends of said piston passageway axially outwardly of said pistons; and manual override means operatively connected to said shaft for manually rotating said shaft, said manual override means including a rod slidably disposed in said rod receiving bore and having wrench surfaces engageable with the wrench surfaces of said bore to prevent relative rotation between said shaft and said rod, said manual override means further including withdrawing means for withdrawing said rod at least partially out of said bore whereby said rod can be gripped and rotated thereby rotating said shaft.
