PURPOSE: An intake pressing device is provided to efficiently reuse an energy by effectively utilizing oil pressure, which is recirculated into an oil pump. CONSTITUTION: External air is introduced into an engine through an intake duct(2). A surge tank(1) is formed at an end of the intake duct(2) in order to distribute intake air into an intake manifold. A throttle valve(3) is formed at an inlet of the surge tank(1). Oil pumped by an oil pump is supplied into each frictional component of an engine through an oil circulation passage(6). A bypass line(11) is formed from the oil circulation passage(6) towards the water pump. A relief valve(7) is formed at an inlet of the bypass line(11) so as to allow oil to be recirculated into the water pump through the bypass line(11) when oil pressure is irregularly formed in the oil circulation passage(6).
