Integrated Pump Pressure Washer

Abstract

An integrated pressure washer is disclosed. The integrated pressure washer has an engine. At the bottom of the engine is an engine bottom cover. The engine bottom cover has a recess formed by a cylindrical wall that extends up from a base of the engine bottom cover. The pressure washer also has a pump assembly. The pump assembly is attached to the engine bottom cover and extends into the recess. The pump assembly receives water and applies pressure to the water and directs the pressurized water out a high pressure hose.

         10 . The single piece engine bottom cover of  claim 9  wherein the continuous wall is cylindrical. 
     
     
         11 . The single piece engine bottom cover of  claim 9  wherein the cooling fins extend along the base. 
     
     
         12 . The single piece engine bottom cover of  claim 9  wherein the engine bottom cover is composed of aluminum. 
     
     
         13 . The single piece engine bottom cover of  claim 9  wherein the pump assembly is an in-line piston pump. 
     
     
         14 . The single piece engine bottom cover of  claim 9  wherein the pump assembly is wobble plate pump. 
     
     
         15 . An integrated pressure washer comprising:
 an engine further comprising an engine bottom cover, the engine bottom cover adapted to receive;   a pump assembly, the pump assembly further comprising
 a recess; 
 a pump manifold, the recess formed by a continuous wall that extends away from the pump manifold; 
   
       wherein the continuous wall of the pump assembly attaches directly to the engine bottom cover the pump assembly receiving water and applying pressure to the water and directing the pressurized water out a high pressure outlet. 
     
     
         16 . The pressure washer of  claim 15  wherein the engine is a vertical shaft engine. 
     
     
         17 . The pressure washer of  claim 15  wherein the engine is a horizontal shaft engine.
