Abstract
A pneumatic actuator includes a housing defining a chamber. A diaphragm is positioned within the chamber. A rod member is attached to the diaphragm and is movable between a first position and a second position. A cam member is attached to the diaphragm and to the rod member. The cam member has a cam surface. A deflection rod has a first end portion and a second end portion, where the first end portion of the deflection rod is attached to the housing. A follower is attached to the second end portion of the deflection rod. The follower engages the cam surface of the cam member so as to urge the rod member towards the second position.
Claims20
A pneumatic actuator comprising:
- a) a housing defining a chamber;
- b) a diaphragm positioned within the chamber;
- c) a rod member attached to the diaphragm, said rod member movable between first position and a second position;
- d) a cam member attached to the diaphragm and to the rod member, said cam member having a cam surface;
- e) a deflection rod having a first end portion and a second end portion, wherein the first end portion of the deflection rod is attached to the housing and the second end portion of the deflection rod is movable along the cam surface;
- f) a follower attached to the second end portion of the deflection rod, said follower engaging the cam surface of the cam member so as to urge the rod member towards the second position.
