Abstract: PURPOSE: A hydraulic control valve apparatus is provided to reduce noise by comprising a stable valve profile with reducing resistances caused by fluid pressure. CONSTITUTION: A hydraulic control valve apparatus comprises a housing unit(10), a hydraulic piston(20), and a bypass unit(30). A lamp protrusion is formed inside the housing unit, and a main chamber(16) and an auxiliary chamber(18) are formed. The hydraulic piston moves back and forth inside the housing unit according to the fluid pressure of the main chamber. A cylinder flow path(22), which is selectively closed by the lamp protrusion is formed in the hydraulic piston. A brake path(24) is formed in a lower part of the cylinder flow path. The bypass unit selectively connects the main chamber and auxiliary chamber.

Abstract: PURPOSE: A variable air intake device is provided to reduce manufacturing cost and prevent torque from being lowered by fabricating the variable air intake device in a simple structure. CONSTITUTION: An inlet(3) of a runner(2) forming an intake manifold is connected to one side of a surge tank(1). A first valve ball(5) and a second valve ball(6) are selectively operated by means of a valve direction switching device. A valve of the valve direction switching device is rotated by means of a rotating shaft(10), which is rotated by fluid flux introduced into the surge tank. A rotating blade(11) is mounted on a front end of the rotating shaft. The rotating shaft is rotatably supported by a supporting member(12). The supporting member is arranged in the surge tank by horizontally crossing the surge tank.
