Abstract: A 2-way pressure balancing valve of a gas feeding apparatus for a gas fuel vehicle is provided to prevent lubrication oil from being excessively discharged even when the pressure in a fuel pump is abruptly changed. A 2-way pressure balancing valve of a gas feeding apparatus for a gas fuel vehicle includes a first pressure balancing passage(831) and a second pressure balancing passage(832). The first and second pressure balancing passages are divided from a pump lubrication connection hole(810) and connected to a bombe connection hole(820). The first and second pressure balancing passages have a first check valve(840) and a second check valve(850) to be operated in opposite directions, respectively. The first check valve installed on the first pressure balancing passage is opened when the pressure of a bombe is larger than that of the lubrication oil.
