Headlamp washer pump

Claim 2

A washer system for sequentially squirting washer fluid onto a plurality of spaced surface areas of an automotive vehicle comprising: a reservoir for containing a supply of washer fluid; pump means including a movable pumping member for pumping washer fluid under pressure, said pump means having an inlet in communication with said reservoir and an outlet through which washer fluid under pressure is emitted; means for energizing said pump means, a valve means having an inlet in communication with the outlet of said pump means and a plurality of spaced outlet ports; a plurality of nozzle means which are adapted to be located adjacent respective ones of the plurality of transparent surface areas, individual ones of said nozzles being in communication with individual ones of said outlet ports, said valve means including a movable valve member which is operatively connected with said pumping member and operable in response to movement of said pumping member, when said pump means is energized, to sequentially uncover individual ones of said outlet ports to sequentially squirt washer fluid onto said plurality of transparent surface areas.

Claim 3

A headlamp washer system for sequentially squirting washer fluid onto a plurality of spaced headlamps of an automotive vehicle comprising: a reservoir for containing a supply of washer fluid; a pump means including a movable pumping member for pumping washer fluid under pressure, said pump means having an inlet in communication with said reservoir and an outlet, means for energizing said pump means, a valve means having an inlet in communication with the outlet of said pump means and a plurality of spaced outlet ports; nozzle means adapted to be positioned adjacent each of the headlamps and with individual ones of the nozzle means being respectively connected with individual ones of the outlet ports of the valve means, said valve means including a valve member which is connected with said movable pumping member and which is movable in response to operation of the pump means to sequentially uncover said outlet ports to sequentially provide a full pressure squirt of washer fluid onto each of the headlamps.

Claim 4

A headlamp washer system for sequentially squirting washer fluid onto a plurality of spaced headlamps of an automotive vehicle comprising: a reservoir for containing a supply of washer fluid; a pump means including a movable pumping member for pumping washer fluid under pressure, said pump means having an inlet in communication with said reservoir and an outlet, means for energizing said pump means, a valve means having an inlet in communication with the outlet of said pump means and a plurality of spaced outlet ports; nozzle means adapted to be positioned adjacent each of the headlamps and with individual ones of the nozzle means being respectively connected with individual ones of the outlet ports of the valve means, said valve means including a valve member which is connected with said movable pumping member and which is movable in response to operation of the pump means to sequentially uncover said outlet ports to sequentially provide a full pressure squirt of washer fluid onto each of the headlamps.

Claim 5

A headlamp washer system for sequentially squirting washer fluid onto a plurality of headlamps of an automotive vehicle comprising: a reservoir for containing a supply of washer fluid; pump means including a reciprocable pumping member for pumping washer fluid under pressure, said pump means having an inlet in communication with the reservoir and an outlet; said pumping member being movable through an intake stroke in which it draws washer fluid from the reservoir into a pumpinG chamber and a discharge stroke, fluid motor means operatively connected with said pumping member for effecting movement of said pump member through its discharge and intake strokes, a valve means having an inlet in communication with the outlet of said pump means and a plurality of spaced outlet ports, nozzle means adapted to be positioned adjacent the headlamps to be washed and with individual ones of the nozzle means being respectively connected to individual ones of said outlet ports, said valve means including a valve member connected to said pumping member and which is reciprocably movable with said pumping member to sequentially uncover said outlet ports to sequentially provide a full pressure squirt of washer fluid onto each of said headlamps in response to movement of said pumping member through its discharge stroke.

Claim 6

A headlamp washer system for sequentially squirting washer fluid onto a plurality of headlamps of an automotive vehicle comprising: a reservoir for containing a supply of washer fluid; pump means including a reciprocable pumping member for pumping washer fluid under pressure, said pump means having an inlet in communication with the reservoir and an outlet; said pumping member being movable through an intake stroke in which it draws washer fluid from the reservoir into a pumpinG chamber and a discharge stroke, fluid motor means operatively connected with said pumping member for effecting movement of said pump member through its discharge and intake strokes, a valve means having an inlet in communication with the outlet of said pump means and a plurality of spaced outlet ports, nozzle means adapted to be positioned adjacent the headlamps to be washed and with individual ones of the nozzle means being respectively connected to individual ones of said outlet ports, said valve means including a valve member connected to said pumping member and which is reciprocably movable with said pumping member to sequentially uncover said outlet ports to sequentially provide a full pressure squirt of washer fluid onto each of said headlamps in response to movement of said pumping member through its discharge stroke.

Claim 7

A headlamp washer system as defined in claim 3 wherein said pumping means and said valve means have a common housing; and wherein said fluid motor is a vacuum-operated fluid motor.

Claim 8

A headlamp washer system as defined in claim 3 wherein said pump means comprises a pump housing having a cylindrical chamber therein, said pumping member is a piston slidably received within said chamber and said valve member is a spool having an annular recess intermediate its ends for sequentially communicating the inlet of the valve means with said outlet ports when moved.
