High pressure solar powered pump
First Claim
1. A high pressure low volume pump assembly comprising a solar panel, a d.c. motor powered by the solar panel and having an output shaft providing at least one cam lobe, a lever abutting the cam and pivotable about an axis, a return mechanism biasing the lever toward the cam, and a reciprocating pump having an input rod and a follower assembly on the input rod abutting the lever so that rotation of the cam causes reciprocation of the input rod thereby powering the reciprocating pump.

Abstract
A solar powered pump assembly delivers high pressure liquid in relatively small volumes. The assembly includes a d.c. motor powered by the solar panel having a gearmotor output shaft driving a multilobe cam which acts against a lever which in turn acts against a follower assembly to reciprocate an input rod of a small reciprocating pump. A voltmeter or voltage measuring circuit is used to detect the voltage output of the solar panel and battery and interrupt operation of the pump assembly in the event the voltage output thereof falls below a predetermined value. A stroke adjustment mechanism may be used to limit the range of oscillating movement of the lever thereby leading to a wide range of daily volume output of the reciprocating pump.
