Relief 'valves are 'commonly used to control this pressure but their operation is unsatisfactory, principally because ofthe corrosion due to the character of the spraying fluids.
The operating mechanism for' the pump may be of various ykinds,'but preferably com .prises a crank shaft 7A journeled in uprights 8 carried by the base 1, and driven by Ineens of gearing 9 and 10 from alshnft 11 to whichv poi-ver may be applied eitherV b u, belt or in# any .other 'suitable manner. o controll the movement of the movable part of the mecha.- nism l have interposed between the samennd another part of the apparatus a two part connecting rod or-togglc, thctwo parts of which are held normally against' relative iovcment by n spring. VIn the present e'mbodiment of the invention the toggle serves4 to transmit power from the shaftto Athe piston und to this end a. toggle is interposed between the crank shaft und each piston.

The movement of this intermediute axis` toward n line extending througlrthenxes 15 and, 16 'of the rod is limited by coperuting parts of the two members of the rod. one member, 13, has :t projection or lug 17 extending beyond the exis 14; sind arranged to engage n part orv lug 18 carried by the other member, 12, of therrod when the two partsA of the rod are moved toward aline-` ment, theerrnngcment of Avthe parts'l'? and 18 being such that the axis14 cannot be As here shown,r
