Fluid-driven reciprocating apparatus and valving for controlling same
Patent
·
OSTI ID:6396133
A liquid pumping system is described comprising: a pair of fluid-driven reciprocating pump assemblies; and a pair of fluid activated valve assemblies operatively connected to each of the pump assemblies; the valve assemblies being interconnected such that stroking of one of the pair of pump assemblies causes activation of the valve assembly connected to the other of the pair of pump assemblies; each of the valve assemblies including a signal means attached to a piston-like member in the pump assembly on which the valve assembly is mounted; whereby stroking of the piston-like member in one of the pump assemblies activates the signal means, which activates the valve assembly of the other of the pump assemblies.
