Abstract
A first inlet port, 38, extends radially through a valve sleeve, 27, into an internal bore, 200. A first outlet port, 38, extends radially outwardly through an outer periphery of the valve sleeve, 27. A second inlet port, 36, on an opposed side of the first outlet port, 38, from the first inlet port, 38, extends radially through a wall of the valve sleeve, 27. A valve spool, 41, is received in the internal bore, 200, and has a first channel, 40, at an outer peripheral surface selectively communicating the first inlet port, 38, to the first outlet port, 42. The valve spool, 41, has a second channel, 32, at the outer peripheral surface that communicates the second inlet port, 36, to an axial vent, 48, formed in an internal surface of the valve sleeve, 27. The axial vent, 48, extends axially to communicate the second channel, 32, to the first outlet port, 42.A pumping system, 20, is also disclosed.
