Abstract
The present disclosure relates to a vibration damper for a hydraulic clutch actuator. The vibration damper comprises a rigid housing comprising a chamber, and an inlet port and an outlet port forming a channel, the channel being in fluid communication with said chamber, and a propeller comprising a plurality of at least two blades, the propeller being rotatably mounted in said chamber, and a spiral torsion spring connected to said propeller in such a way that rotation of the propeller causes winding or unwinding of the spring.

A vibration damper for a hydraulic clutch actuator system, comprising:
- a rigid housing comprising a chamber;
- an inlet port and an outlet port and a channel fluidly connecting the inlet port and the outlet port;
- a propeller comprising a plurality of blades, the propeller being rotatably mounted in said chamber;
- the chamber being fluidly connected with the channel in such a way that movement of fluid through the channel causes rotation of the propeller;
- a spiral torsion spring operatively connected to said propeller in such a way that rotation of the propeller causes winding or unwinding of the spring.
A hydraulic actuation system for a vehicle, comprising:
- a master cylinder connectable to a clutch pedal;
- a slave cylinder connectable to a clutch of a motor;
- a vibration damper comprising:
- a rigid housing delimiting a hollow chamber;
- an inlet port and an outlet port connected by a channel configured to pass a hydraulic fluid from the master cylinder to the slave cylinder;
- a propeller operatively mounted on a rotatable shaft and connected to a spiral torsion spring to allow rotation of the said spring;
- and
- a sealing element fixed inside the housing and mounted above the propeller;
- a first hydraulic line connected between the master cylinder and the inlet port of the vibration damper;
- a second hydraulic line connected between the outlet port of the vibration damper and the slave cylinder.
A vibration damper system arranged between a master cylinder and a slave cylinder of a hydraulic actuator system, comprising:
- an inlet port that connects the master cylinder via a first hydraulic line;
- an outlet port that connects the slave cylinder via a second hydraulic line;
- wherein the first and second hydraulic lines are configured to provide movement of hydraulic fluid between the master cylinder and the slave cylinder;
- a housing comprising a cylindrical wall and a bottom wall and enclosing a hollow chamber;
- a propeller comprising of a plurality of blades mounted on a rotatable shaft held via a first bearing;
- the rotatable shaft comprising of an upper end connected to a second bearing;
- a spiral torsional spring connected to the propeller via the second bearing;
- a sealing element arranged between the propeller and the spring such that hydraulic fluid is in direct contact with the propeller but not the spring;
- and
- a removable cap positioned on an upper side of the housing.
