Abstract: A voltage regulator includes a static regulator that provides a static regulated supply output as a reference input to a dynamic regulator to provide a regulated supply voltage. In one embodiment, multiple dynamic regulators are connected to the static regulated supply output of the static regulator. The one or more dynamic regulators dynamically detect when the regulated supply voltage is loaded below a predetermined reference level, and provide extra current in response to prevent the regulated supply voltage from drooping. Since the static regulator is capable of handling large average currents, the dynamic regulator circuit can be smaller than a typical dynamic regulator for an equivalent load. Furthermore, since the dynamic regulator provides transient current requirements, the size of the static regulator may be likewise smaller in size than a typical static regulator for an equivalent load.

Abstract: The present invention is directed to a wobble piston and seal assembly for an oil free compressor. An upwardly directed curvature is provided on a piston surface which supports the seal. The curvature is located adjacent the perimeter of the surface to impart a slight dish shape to the surface. Preferably, the curvature has the same radius as the bend radius of the seal when the piston head is inserted into a cylinder. When the seal is initially clamped to the support surface, the seal is formed to take on the curvature of the support surface. Consequently, the seal is preformed into a shallow cup shape prior to final forming when the piston and seal assembly are inserted into a cylinder.
