Abstract
A fluid deceleration device is provided for a hydraulic system having a housing forming a sump, and a valve unit having an outlet port through which hydraulic fluid is expelled for communication to the sump. The fluid deceleration device includes an elongated tilted fluid container and a conduit which communicates fluid from the outlet port to an interior of the container. The container has an upper open end surrounded by a lip. When the container is filled, de-aerated fluid spills over the lip and falls into the sump.

In a hydraulic system having a housing forming a sump, and a valve unit having an outlet port through which hydraulic fluid is expelled for communication to the sump, characterized by:
- a fluid deceleration/de-aeration device comprising a fluid container and a conduit communicating fluid from the outlet port to an interior of the container, the container having an opening surrounded by a lip over which fluid spills into the sump when the container is filled, the container having a closed end and an open end, the container having an inner wall which is fixed to a portion of the conduit, and the conduit having an outlet end which is received by the container.
In a hydraulic system having a housing forming a sump, and a valve unit having an outlet port through which hydraulic fluid is expelled for communication to the sump, characterized by:
- a fluid container spaced apart from and above the sump;
- and
- a conduit communicating fluid from the outlet port to the container, the container holding the fluid while it de-aerates, de-aerated fluid spilling out of the container and falling into the sump, the container is elongated and has a central axis which extends at an angle between horizontal and vertical.
In a hydraulic system having a housing forming a sump, and a valve unit having an outlet port through which hydraulic fluid is expelled for communication to the sump, characterized by:
- a fluid deceleration/de-aeration device comprising a fluid container and a conduit communicating fluid from the outlet port to an interior of the container, the container having an opening surrounded by a lip over which fluid spills into the sump when the container is filled, and the conduit being routed over a side surface and a top surface of the valve unit.
