Abstract: A hydraulic type scissors gear removes factors that generate a backlash due to reduction of tension of existing springs by generating a relative motion between gears using oil pressure. The hydraulic type scissors gear includes: a first gear having an operation chamber and supplied with oil in the operation chamber; a second gear coaxially disposed on a side of the first gear to be rotate relative to the first gear; and a piston configured to rotate the second gear by applying force that pushes the second gear in a rotational direction opposite to a rotational direction of the first gear by being moved in the operation chamber by oil pressure supplied to the operation chamber.

Abstract: A compression release type of engine brake socket module is provided between an exhaust rocker arm rotating with respect to a rocker arm shaft and a valve bridge connecting an exhaust valve of an engine. In particular the socket module incudes: a housing which includes an inlet through which brake oil is introduced, a brake piston mounting portion, and a reset member mounting portion communicating with the brake piston mounting portion; a brake piston that is provided to be movable in the brake piston mounting portion; a stopper disposed on one side of an inner space of the housing to limit a moving position of the brake piston; and a reset member that is provided in the reset member mounting portion, and that discharges the brake oil by selectively contacting a push pin coupled to an upper portion of a cylinder head.

Abstract: A valve opening and closing apparatus includes a rocker arm which is in contact with a cam and causes a valve to be opened and closed using rotation of the cam. In particular, the valve opening and closing apparatus includes an eccentricity-creating unit which is disposed on the rocker arm and changes an eccentric position using rotation. A contact-maintaining unit of the valve opening and closing apparatus is disposed between the rocker arm and the eccentricity-creating unit so as to maintain the contact between the cam and the rocker arm when the cam is rotating.
