Abstract
A system for filtering hydraulic fluid that is periodically pressurized by a compensation cylinder attached to an external load. A first filter, a first flow control valve that passes fluid from the compensation cylinder under a first higher pressure to the first filter, and a second flow control valve that passes fluid back to the compensation cylinder when the compensation cylinder produces a second lower pressure.
Claims20
A system for filtering hydraulic fluid operating in a motion compensation system comprising:
- an inlet filter hydraulically connected to the motion compensation system via a first flow control valve to receive a portion of hydraulic fluid passed under pressure from the motion compensation system to the accumulator;
- and
- an outlet filter hydraulically connected to the motion compensation system via a second flow control valve;
- wherein the outlet filter is hydraulically connected to the inlet filter to return at least a portion of the hydraulic fluid received at the inlet filter back to the motion compensation system when the motion compensation system reduces an internal pressure.
A system for filtering hydraulic fluid that is periodically pressurized by a motion compensation system attached to an external load, the system for filtering hydraulic fluid comprising:
- a first filter;
- a first flow control valve that passes fluid from the motion compensation system under a first higher pressure to the first filter;
- and
- a second flow control valve that passes fluid back to the motion compensation system when the motion compensation system produces a second lower pressure.
A method for filtering hydraulic fluid circulating from a motion compensation system at periodic first higher pressures and second lower pressures comprising:
- receiving the hydraulic fluid from the motion compensation system at the first higher pressure through a first flow control valve and a first filter;
- and
- returning the hydraulic fluid to the motion compensation system at the second lower pressure through a second flow control valve.
