Hydraulic power and control system

Abstract

A hydraulic power and control system which includes a pump which is mounted n a sealed housing. The pump is mounted in the sealed housing along with a pilot operated power valve. The pump has an inlet within the housing for intaking oil therein and is connected to the pilot operated power valve for operating components in a functional system, such as a submersible docking apparatus. The pilot operated power valve discharges oil into the sealed housing and is connected to a control valve which is located exterior of the housing. The control valve will pilot operate the power valve and discharges oil within the sealed housing. The control valve may be mounted within a pressure casing which receives a reduced oil pressure from the pump within the sealed housing. The sealed housing may be pressure compensated to ambient so that the pressure casing is maintained at a specific pressure level above ambient. Further, the control valve in the pressure casing may have push buttons which sealably extend exteriorly therefrom for operation by a diver.
