Patents by Inventor Paul T. Kubinski

Paul T. Kubinski has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8161742
    Abstract: An electro-hydraulic actuator includes a hydraulic pump, an electric motor operatively connected to the hydraulic pump and operable for driving the pump, an actuator moveable in response to fluid flow from the pump, and a housing for the pump, electric motor and actuator. The housing has a base member that is adapted to be modified into various configurations for forming an attachment interface for mounting of the electro-hydraulic actuator.
    Type: Grant

  • Patent number: 7546730
    Abstract: A stabilizer system and method that can provide high speed, relatively low force extension and retraction of a stabilizer leg during a first portion of a stroke, and low speed, relatively high force extension and retraction during a second portion of the stroke. Accordingly, the stabilizer system and method takes less time to deploy than conventional stabilizer systems but without sacrificing performance.

  • Patent number: 7513809
    Abstract: A tilt actuator for an outboard motor wherein shocks acting on the actuator are initially dissipated at a first damping rate and then at a higher damping rate near the end-of-stroke of the actuator's piston. The tilt actuator comprises a cylinder, a piston, a piston rod and a damper member, the latter being cooperative with the piston in a first position to at least partially block at least one of plural damping passages in the piston thereby to restrict flow of fluid from the first chamber to the damping passages in the piston and in a second position that allows full damping flow of fluid to the inlet openings of the damping passages from the first chamber to the damping passages in the piston during movement of the piston in the second direction.

  • Patent number: 6886332
    Abstract: A hydraulic system for an actuator provides staged operation during extend and retract. A pair of reversible pumps are conjointly driven by a reversible motor. A relief valve in the retract circuit directs fluid to tank when fluid pressure increases above a predetermined value. An unloader valve in the extend circuit is responsive to pressure at a first stage pump to direct flow to tank when the pressure increases above a second predetermined value. A non-return check valve connected between the pumps in the extend circuit closes the flow circuit to the second stage pump during high loads, so that the flow from the second stage pump goes to tank, and the return flow from the actuator goes only to the first stage pump. The non-return check valve is responsive (via a signal line to the retract circuit portion) to the pressure in the extend and retract circuit portions.
