Abstract
A four-way fluid flow control valve for selectively interconnecting opposite sides of a fluid motor with a source of fluid pressure and a low pressure return line for driving the motor in opposite directions. A clevis-like, bifurcated metering member has opposed, cup-shaped elements at its bifurcated end which are shiftable across opposed, flat surfaces to produce the desired fluid flow interconnections. The cup-like elements present fluid transfer zones for selectively interconnecting different fluid flow passages.
