ABSTRACT:
An oilless high pressure pump suitable for use in devices such as pressure washers and the like is described. The pump includes an eccentric assembly suitable for converting rotary motion of a rotating shaft to rectilinear motion. One or more straps couple the eccentric assembly to a piston assembly. The straps communicate the rectilinear motion of the eccentric assembly to the piston assembly, reciprocating the piston assembly to pump the liquid.
