A condition of flow in a passage that is typified by slow movement of fluid in a relatively straight path along the centerline of the passage.
A term loosely applied to almost any moving cylindrically shaped part of a hydraulic component which moves to direct flow through the component.
The pressure in the pilot circuit.
The opposition to current flow offered by the components, conductors and load.
A mechanical device used to attach two pieces of tubing/pipe together or to attach a piece of tubing/pipe to a component.
Energy that a substance or body has by virtue of its mass and velocity.
The volume of fluid discharged by a pump in a given time. Usually expressed in GPM.
The form of energy that has the capacity to create warmth or to increase the temperature of a substance.
A condition of equal opposed hydraulic forces acting on a part in a hydraulic component.
A secondary passage for fluid flow.
A valve that allows fluid flow in one direction, yet stops flow in the opposite direction.
A passage used to transport fluid between components in a fluid power system. Normally constructed from multiple layers of rubber or other synthetic materials.
The volume mass, or weight of a fluid passing through any conductor per unit of time.
A cylindrically shaped part which fits within a cylinder.
A device for converting hydraulic energy into mechanical energy.
A narrowing of the passage size.
A passage in, or line from a hydraulic component which returns fluid independently to reservoir.
A mechanical device fitted into a hydraulic cylinder that closes off the flow path of fluid to effect a smooth deceleration and stop to the cylinder at the end of the stroke.
