Definitions
- the hydraulic actuator may serve to actuate the friction clutch between the disengaged operating position and the engaged operating position.
- the actuating device may comprise a master cylinder, a slave cylinder and a hydraulic pressure line connecting the master cylinder and the slave cylinder.
- the master cylinder may be operatively connected to a clutch pedal.
- the master cylinder can be actuation connected under kinematic interposition of a piston rod with the clutch pedal.
- the slave cylinder may be operatively connected to the friction clutch.
- the slave cylinder can be actuated connected under kinematic interposition of a release bearing with the friction clutch.
- a hydraulic ratio can be formed between the master cylinder and the slave cylinder.
- a damped hydraulic path can be formed between the master cylinder and the slave cylinder.
- the piston can be displaced in the axial direction.
- the piston can be displaceable along a longitudinal axis of the housing.
- the piston may have at least one seal for sealing against the housing.
- the piston may have a first seal and a second seal for sealing against the housing.
- the seal may be a radial seal.
- the seal can be a rubber seal.
- the seal may be a lip seal.
- the invention thus provides inter alia a master cylinder with a preload spring in a cylinder of a secondary seal, in which the compression spring is installed in the cylinder of the secondary seal, so that the spring does not disturb the magnetic field.
- the spring can be installed in the cylinder of the secondary seal.
- the compression spring can be centered on the piston and axially supported.
- At the housing se can be added behind a slope on a follower groove a small undercut on which the compression spring can be axially supported. If the centering ring is firmly connected to the piston, the function of the compression spring is maintained, d. h all parts inside are pushed back.
- the advantage here is that the spring is removed from the magnetic field.
- the interior 104 has two openings 124, 126.
- the opening 124 is an opening of the interior section 112.
- the opening 126 is an opening of the interior section 114.
- the opening 124 is arranged on the end of the interior section 112 facing away from the piston rod 110.
- the opening 126 is arranged on the end of the interior portion 1 14 facing away from the piston rod 110.
- the housing 102 has a connecting piece 128 of the opening 124 and a connecting piece 130 of the opening 126.
- a pressure line for hydraulic connection to a slave cylinder can be connected.
- a supply line can be connected.
