Abstract

A plunger pump suitable for an apparatus for injecting liquid under high pressure through a plurality of nozzles (104) into the turf. A plunger (34) of the pump is connected through a connecting rod (39) to a crank shaft (12) for the reciprocation thereof, and the crank shaft is more quickly rotated through its angle of rotation at the discharge stroke than through the angle of rotation at the suction stroke of the plunger to increase discharge pressure of the liquid upon its intermittent injection.
