Pump housing with multiple discharge valves

Abstract

A plunger pump fluid end housing assembly comprising: a fluid end housing, multiple plungers a single suction valve and seat corresponding with each said plunger, and one or more discharge valves and seats corresponding with each said plunger; wherein axes of said suction valve and seat are parallel with said plunger, the axes of said discharge valves and seats are substantially parallel to each other and perpendicular to the said plunger axis, and the suction manifold is positioned to feed the fluid chamber opposite the power end of the fluid end.

What is claimed is: 
     
         1 . A plunger pump fluid end housing with multiple fluid chambers arranged in a longitudinal plane and each fluid chamber comprising:
 a suction bore;   a plunger bore;   a plurality of discharge bores;   wherein the axis of said suction bore and the axis of said plunger bore are parallel, and   wherein the axis of each individual discharge bore in said plurality of discharge bores is parallel to the axes of the other individual discharge bores in said plurality of discharge bores and also is substantially perpendicular to said suction bore axis.   
     
     
         2 . A plunger pump fluid end housing of  claim 1  wherein each fluid chamber contains two discharge bores. 
     
     
         3 . A plunger pump fluid end housing of  claim 1  wherein the axis of said plunger bore is substantially collinear with the axis of said suction bore. 
     
     
         4 . A plunger pump fluid end housing of  claim 1  wherein the area of either discharge port in said discharge bore equals approximately half the area of the suction port in said suction bore. 
     
     
         5 . A plunger pump fluid end housing of  claim 1  wherein the axes of the said individual discharge bores within said plurality of discharge bores are substantially collinear. 
     
     
         6 . A plunger pump fluid end housing of  claim 1  wherein the suction manifold ports of said housing are positioned on the fluid end housing opposite to the power end of the plunger pump. 
     
     
         7 . A plunger pump fluid end housing assembly comprising:
 a fluid end housing;   a plurality of plungers;   a single suction valve and seat corresponding to each individual plunger in said plurality of plungers;   a plurality of discharge valves and seats corresponding to each individual plunger in said plurality of plungers;   wherein the axis of each said suction valve and seat is parallel to each of said individual plungers in said plurality of plungers; and   wherein the axes of each of the individual discharge valves in said plurality of discharge valves and seats is parallel and substantially perpendicular to the respective axis of each of the said individual plungers, suction valves, and suction seats.   
     
     
         8 . A plunger pump fluid end housing of  claim 7 , wherein each fluid chamber contains two discharge valves and two discharge seats. 
     
     
         9 . A plunger pump fluid end housing assembly of  claim 8 , wherein each axis of said individual plungers is substantially collinear with the corresponding axis each of said individual suction valves and corresponding individual valve seats. 
     
     
         10 . A plunger pump fluid end housing assembly of  claim 7 , wherein the flow area of either discharge seat of said assembly equals approximately half the flow area of said suction seat in said housing. 
     
     
         11 . A plunger pump fluid end housing of  claim 7 , wherein the axes of said multiple discharge valves and seats are substantially collinear. 
     
     
         12 . A plunger pump fluid end housing of  claim 7 , wherein the suction manifold of said housing assembly is positioned opposite to the power end of the plunger pump.
