Abstract
There is provided a variable valve apparatus including: a plurality of rocker arms; a coupling pin disposed in a housing hole of the rocker arm closer to one side; a release pin disposed in a housing hole of the rocker arm closer to the other side; a pressing member; a transmission member; and a push-back member disposed so as to push back the transmission member from the other side. The pressing member is configured to push the coupling pin into the housing hole of the rocker arm closer to the other side to couple the plurality of rocker arms. The transmission member is configured to push back the coupling pin into the housing hole of the rocker arm closer to the one side to release a coupling of the plurality of rocker arms.

A variable valve apparatus configured to change a valve operation in a cylinder head, the variable valve apparatus comprising:
- a rocker shaft configured to extend from one side of the cylinder head to the other side of the cylinder head inside the cylinder head;
- a plurality of rocker arms configured to swing around an axis of the rocker shaft;
- a coupling pin disposed in a housing hole of the rocker arm closer to one side of the cylinder head in an axial direction;
- a release pin disposed in a housing hole of the rocker arm closer to the other side of the cylinder head in the axial direction;
- a pressing member disposed on the one side of the cylinder head with respect to the rocker arm closer to the one side of the cylinder head;
- a transmission member disposed on the other side of the cylinder head with respect to the rocker arm closer to the other side of the cylinder head;
- and
- a push-back member disposed on the other side of the cylinder head with respect to the rocker arm closer to the other side of the cylinder head so as to push back the transmission member from the other side of the cylinder head,
- wherein the pressing member is configured to push the coupling pin into the housing hole of the rocker arm closer to the other side of the cylinder head while pushing the release pin out toward the other side of the cylinder head to couple the plurality of rocker arms, and
- wherein the transmission member is configured to be pushed back by the push-back member and to push back the coupling pin into the housing hole of the rocker arm closer to the one side of the cylinder head via the release pin to release a coupling of the plurality of rocker arms.

- a plurality of rocker arms configured to swing around an axis of the rocker shaft;
- a coupling pin disposed in a housing hole of the rocker arm closer to one side of the cylinder head in an axial direction;
- a release pin disposed in a housing hole of the rocker arm closer to the other side of the cylinder head in the axial direction;
- a pressing member disposed on the one side of the cylinder head with respect to the rocker arm closer to the one side of the cylinder head;
- a transmission member disposed on the other side of the cylinder head with respect to the rocker arm closer to the other side of the cylinder head;
- a push-back member disposed so as to push back the transmission member from the other side of the cylinder head;
- and
- a sensor disposed on the other side of the cylinder hear with respect to the push-back member,
- wherein the pressing member is configured to push the coupling pin into the housing hole of the rocker arm closer to the other side of the cylinder head while pushing the release pin out toward the other side of the cylinder head to couple the plurality of rocker arms,
- wherein the transmission member is configured to be pushed back by the push-back member and to push back the coupling pin into the housing hole of the rocker arm closer to the one side of the cylinder head via the release pin to release a coupling of the plurality of rocker arms,
- wherein the sensor is configured to detect a coupled state and a released state of the plurality of rocker arms,
- wherein a rod configured to extend toward the sensor is formed on the transmission member, and
- wherein the sensor is configured to detect the coupled state and the released state of the plurality of rocker arms based on movement of the rod.
