Abstract
A regulator for clutch actuator includes a housing having a cylindrical damping space inside, a first fluid path interconnecting the damping space and a master cylinder, and a second fluid path interconnecting the damping space and a an operating cylinder. The regulator further includes a flexible valve member contained in the damping space for reducing vibrations. The flexible valve member comprises a first inflow guiding portion configured to receive and guide fluid from the first fluid path. The first inflow guiding portion has a plurality of through holes such that elastic deformation of the first inflow guiding portion reduces vibration when fluid flow into the cylindrical damping space from the master cylinder.
Claims11
A regulator for clutch actuator comprising:
- a housing having a cylindrical damping space provided inside, a first fluid path communicating a hydraulic line connected to a master cylinder and one end of the damping space, and a second fluid path communicating a hydraulic line connected to an operating cylinder and the other end of the damping space;
- and
- a valve member accommodated in the damping space to open and close a flow path and reduce vibration,
- wherein the valve member comprises
- a compartment portion configured to divide the inside of the damping space into semi-circular first space and second space;
- a first inflow guiding recess formed at one end of the compartment portion facing the first fluid path to communicate the first fluid path and the first space and second space;
- a second inflow guiding recess formed at the other end of the compartment portion facing the second fluid path to communicate the second fluid path and the first space and second space;
- a first open/close portion provided on one side of the compartment portion to open or close the first space, allowing a fluid to flow from the first fluid path to the second fluid path;
- and
- a second open/close portion provided on the other side of the compartment portion to open or close the second space, allowing a fluid to flow from the second fluid path to the first fluid path,
- wherein the valve member is integrally formed of a deformable material.
A regulator for clutch actuator comprising:
- a housing having a cylindrical damping space provided inside, a first fluid path communicating a hydraulic line connected to a master cylinder and one end of the damping space, and a second fluid path communicating a hydraulic line connected to an operating cylinder and the other end of the damping space;
- and
- a valve member contained in the damping space to reduce vibrations by elastic deformation while opening or closing a fluid path,
- wherein the valve member comprises
- a first open/close portion configured to open or close a fluid path in the damping space to allow a fluid to flow from the first fluid path to the second fluid path and block a counter flow;
- and
- a second open/close portion configured to open or close a fluid path in the damping space to allow a fluid to flow from the second fluid path to the first fluid path and block a counter flow,
- wherein the valve member is integrally formed of a deformable material.
