Abstract
A pneumatic reciprocator includes a cylindrical air cylinder concentrically mounted within a cylindrical manifold. A cylindrical sleeve valve is concentrically mounted for movement along the manifold by a pair of spaced O rings. Two sets of circumferentially arranged air holes in the manifold are alternately covered and uncovered by the O rings as the sleeve valve is moved to selectively pressurize and vent opposite sides of the piston in the air cylinder. Movement of the sleeve valve is controlled by stops on the movable bed of a surface grinder that is controlled by the air cylinder.
Claims11
A pneumatic reciprocator comprising:
- an air cylinder including a movable piston assembly and air passageways;
- manifold means substantially surrounding said air cylinder and isolating said air passageways;
- and
- sleeve valve means movably mounted on said manifold means for supplying compressed air to said air passageways in accordance with the position of said sleeve valve means on said manifold means.
A pneumatic reciprocator comprising:
- a cylindrical air cylinder including a movable piston assembly and air passageways;
- cylindrical manifold means substantially surrounding said air cylinder and isolating said air passageways;
- cylindrical sleeve valve means including spaced apart resilient annular seal means engaging said manifold means, said sleeve valve means being movable back and forth along said manifold means for supplying compressed air to said air cylinder via said air passageways;
- and
- two sets of circumferentially arranged and spaced apart air holes in said manifold means in respective communication with said air passageways.
