Abstract
A double-acting reciprocating pump comprises a piston assembly comprising at least one piston disposed within at least one piston cylinder for undergoing opposite reciprocal movements within said at least one piston cylinder, an upper pump chamber disposed above the piston, and a lower pump chamber disposed below the piston. A fluid inlet is fluidically connected to one of the upper and lower pump chambers so as to supply fluid thereto, and a fluid outlet dispensing port is defined within a lower end portion of the double-acting reciprocating pump assembly for permitting fluid to be dispensed out from the double-acting reciprocating pump assembly during both of the opposite reciprocal movements.
Claims7
A double-acting reciprocating pump assembly for dispensing a fluid, comprising:
- a piston assembly comprising at least one piston disposed within at least one piston cylinder, defined around a longitudinal axis and having a predetermined length dimension, wherein said at least one piston undergoes opposite reciprocal movements within said at least one piston cylinder along said longitudinal axis;
- an upper pump chamber disposed above said at least one piston, and a lower pump chamber disposed below said at least one piston;
- a fluid inlet port fluidically connected to a material supply of fluid to be dispensed and fluidically connected to one of said upper and lower pump chambers so as to supply the fluid to be dispensed to said one of said upper and lower pump chambers;
- a fluid conduit fluidically connected to one of said upper and lower pump chambers, extending longitudinally throughout said predetermined length dimension of said at least one piston cylinder, and disposed coaxially with respect to said at least one piston cylinder defined around said longitudinal axis;
- and a fluid outlet dispensing port defined within a lower end portion of said double-acting reciprocating pump assembly and fluidically connected to said fluid conduit for permitting the fluid to be dispensed out from said double-acting reciprocating pump assembly during both of said opposite reciprocal movements.
