Abstract:
A piston pump arrangement that disables operation of the pump in the absence of an inlet liquid and also to a piston pump arrangement useful to discharge liquids from at least two sources and to disable discharge of all of the liquids when supply of liquid from at least one source is empty.

Claim (Index 6):
A pump arrangement as claimed in  claim 1  including:\n a second piston pump having a second chamber and a second piston reciprocally movable along a second axis in the second chamber to draw a second fluid into the second chamber from a second reservoir through a second conduit opening into the second chamber and discharge the second fluid out a second outlet, \n the second axis parallel to the first axis, \n wherein reciprocal movement of the second piston discharges the second fluid from the second reservoir until the second reservoir is empty of the second fluid wherein further reciprocal movement of the second piston creates a vacuum condition in second chamber axially inward of the second piston, \n a coupling bridge member mechanically linking the first piston and the second piston together to form a driven member carrying the first piston and second piston mechanically linked with the bridge member for movement in unison parallel the first axis, \n the driving member coupled to the driven member by the releasable juncture arrangement, \n in the coupled condition of the releasable juncture arrangement, the releasable juncture arrangement securing the driving member and the driven member together for reciprocal movement along the axis in unison, \n in the uncoupled condition of the releasable juncture arrangement, the movement of the driving member does not move the driven member rendering both the first piston pump inoperative to discharge the first fluid by movement of the driving member and the second piston pump inoperative to discharge the second fluid by movement of the driving member, \n with the releasable juncture arrangement in the coupled condition, when either the vacuum condition in the first chamber is greater than the threshold separation vacuum or the vacuum condition in the second chamber is greater than the threshold separation vacuum, the releasable juncture arrangement assumes the uncoupled condition.
