Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
116 words
A portable fluid sprayer comprising, a pump, a motor adapted to drive said pump, conduit means interconnecting a replaceable reservoir to said pump and leading to a discharge opening, said conduit means having a spring-biased normally closed control valve assembly operatively disposed between said pump and said discharge opening and movable between valve-open and valve-closed positions, said valve assembly including an integral extension having electrically conductive contact means for completing an electrical circuit between a source of power and said motor when said valve is in the valve-open position, and disconnecting said circuit when said valve is in the valve-closed position, said valve assembly including stop means for limiting travel between the valve-open and valve-closed positions.
Claim 2
Dependent Claim
116 words
A portable fluid sprayer comprising, a pump, a motor adapted to drive said pump, conduit means interconnecting a replaceable reservoir to said pump and leading to a discharge opening, said conduit means having a spring-biased normally closed control valve assembly operatively disposed between said pump and said discharge opening and movable between valve-open and valve-closed positions, said valve assembly including an integral extension having electrically conductive contact means for completing an electrical circuit between a source of power and said motor when said valve is in the valve-open position, and disconnecting said circuit when said valve is in the valve-closed position, said valve assembly including stop means for limiting travel between the valve-open and valve-closed positions.
Claim 3
Dependent Claim
106 words
A portable fluid sprayer comprising, a replaceable reservoir containing a supply of fluid, a diaphragm-type piston pump with a pump inlet interconnected with said reservoir, an electric motor-driven cam means for operating said piston pump, ball check valves for controlling fluid inlet to and outlet from said pump, connecting conduit means from a pump outlet to a discharge valve chamber, a spring-biased normally closed control valve assembly adapted to be selectively opened for discharge of said fluid, said valve assembly including an integral electrically conductive plunger means for simultaneously completing an electrical circuit in order to energize said electric motor and open said discharge valve means.
Claim 4
Dependent Claim
106 words
A portable fluid sprayer comprising, a replaceable reservoir containing a supply of fluid, a diaphragm-type piston pump with a pump inlet interconnected with said reservoir, an electric motor-driven cam means for operating said piston pump, ball check valves for controlling fluid inlet to and outlet from said pump, connecting conduit means from a pump outlet to a discharge valve chamber, a spring-biased normally closed control valve assembly adapted to be selectively opened for discharge of said fluid, said valve assembly including an integral electrically conductive plunger means for simultaneously completing an electrical circuit in order to energize said electric motor and open said discharge valve means.
Claim 5
Dependent Claim
34 words
The portable sprayer of claim 2 in which said discharge valve assembly is linearly movable between valve-closed and valve-opened positions, said valve assembly including stop means for limiting the travel of said valve assembly.
Claim 6
Dependent Claim
118 words
A portable fluid sprayer comprising a frame means, a motor operated pump and a replaceable reservoir mounted on said frame, conduit means interconnecting said reservoir, said pump and a discharge opening, said conduit means having a control valve assembly including an operating plunger operatively positioned between said pump and said discharge opening and movable between valve-open and valve-closed positions, the operating plunger of said valve assembly having an integral electrically conductive extension for completing an electric circuit to said motor-operated pump when said valve is in the valve-open position, and said electric circuit being interrupted when said control valve is in the valve-closed position, said control valve assembly including stop means for limiting the travel of said plunger.
Claim 7
Dependent Claim
118 words
A portable fluid sprayer comprising a frame means, a motor operated pump and a replaceable reservoir mounted on said frame, conduit means interconnecting said reservoir, said pump and a discharge opening, said conduit means having a control valve assembly including an operating plunger operatively positioned between said pump and said discharge opening and movable between valve-open and valve-closed positions, the operating plunger of said valve assembly having an integral electrically conductive extension for completing an electric circuit to said motor-operated pump when said valve is in the valve-open position, and said electric circuit being interrupted when said control valve is in the valve-closed position, said control valve assembly including stop means for limiting the travel of said plunger.
