Bidirectional piston pump

Abstract

A two-way mechanical pump for a steam appliance having a main body having a boiler with a water inlet and a steam outlet positioned therein in provided. The bidirectional pump on two-way piston pump in accordance with the invention includes a cylinder separated into two chambers by a piston coupled to a piston rod or appliance handle. An inlet having a one-way valve and an outlet having a one-way valve are connected to each change. Movement of the piston from the first end of the cylinder to the second end expels liquid out of the second end and outlet and draws water into the first chamber through the first inlet and one-way valve and movement of the piston towards the first and expels water out of the first chamber and outlet through the first outlet valve and draws water into the second chamber through the second inlet and inlet valve.

1 . A two-way mechanical pump, comprising:
 a pump cylinder having a first end and a second end;   a piston moveably positioned in the cylinder and dividing the cylinder into a first chamber at the first end, and a second chamber at the second end;   a first inlet connected to the first chamber of the cylinder with a first one-way inlet valve in the first inlet, and a second inlet connected to the second chamber of the cylinder with a second one-way inlet valve on the second inlet;   a first outlet connected to the first chamber of the cylinder with a first one-way outlet valve in the first outlet, and a second outlet connected to the second chamber of the cylinder with a second one-way outlet valve in the second outlet.   
   
   
       2 . The two-way pump of  claim 1 , wherein the first and second inlets are connected to a common water source. 
   
   
       3 . The two-way pump of  claim 1 , wherein the first and second outlets are connected to a common outlet. 
   
   
       4 . The two-way pump of  claim 1 , wherein the outlet is connected to a steam generator.
