CONTACTLESS DISPLACEMENT TYPE FUEL PUMP FOR L P G VEHICLE

摘要

A contactless displacement type fuel pump for LPG vehicle is provided to give the piston rod flexibility and maintain a constant gap between the pump body and the piston. A contactless displacement type fuel pump for LPG vehicle comprises a pump body(200) in which an inlet(210) and an outlet(220) are formed, a piston(300) installed on the pump body, a linear motor(400) reciprocating the piston, and a linear flexion bearing(100) arranged on both sides of the linear motor. The linear motor strongly supports the piston rod in the radial direction so that the piston reciprocating in the pump body is fixed at the specific position.
