A control valve suitable for use with a tire and pump assembly is described that controls the flow of air from the pump into the tire. The control valve includes an optional bi-directional feature. The pathways alternatively operate to deliver ambient non-pressurized air to the air pumping tube in response to directional tire rotation against a ground surface.

Valve regulator

A fluid power cylinder provided with a clamp to allow for clamping of the cylinder to another surface, or for clamping of an object onto the cylinder housing without applying forces directly on an inner bore of the cylinder and without causing any distortion of the bore diameter surface of the cylinder in which a piston is running.

Apparatus and method for providing a clamp on a fluid power cylinder

A sorting machine for diverting an article from an article stream generally includes a manifold, a first valve supported on the manifold and a second valve supported on top of the first valve. The manifold has a first blow-off conduit and a second blow-off conduit formed therein. The first blow-off conduit terminates at a first blow-off port and the second blow-off conduit terminates at a second blow-off port. The first valve is in fluid communication with the first blow-off conduit of the manifold for supplying a burst of fluid out of the manifold through the first blow-off port to divert an article from an article stream intersecting with the first blow-off port. The first valve further has a by-pass duct in fluid communication with the second blow-off conduit of the manifold. The second valve is in fluid communication with the by-pass duct of the first valve for supplying a burst of fluid out of the manifold through the second blow-off port to divert an article from an article stream intersecting with said second blow-off port. In this manner, the space between the first and second blow-off ports of the manifold can be made less than the width of the first valve.
