| 192850480 | Operator rotatable relative to clutch input and output | 7 |
| 192850490 | And aligned with clutch axis of rotation | 3 |
| 20100051407 | Hydraulic Coupling - A torque transfer coupling includes first and second rotary members. A transfer clutch operatively connects the first and second rotary members. A piston, disposed in a piston chamber, is actuable to engage the transfer clutch. A hydraulic pump in fluid communication with a sump containing hydraulic fluid has a first pump member fixed for rotation with the first rotary member and a second pump member fixed for rotation with the second rotary member such that relative rotation between the first and the second pump members generates a fluid pumping action. A first flow path supplies hydraulic fluid from the hydraulic pump to the piston chamber. A second flow path supplies hydraulic fluid from the piston chamber to a control valve for regulating the pressure of the hydraulic fluid supplied to the piston chamber. The second flow path includes an aperture extending through the second pump member. | 03-04-2010 |
| 20150308517 | Fluid Actuated Over-Center Clutch for a PTO - A hollow double-acting cylinder assembly may be mounted over a shaft and to a housing. A moveable piston of the cylinder assembly connects to a sliding sleeve of an over-center mechanism and the sliding sleeve with a thrust bearing allowing it to push and pull the sleeve mechanism with cylinder action. A toggle action of the over-center mechanism locks clutch without the need to sustain pressure on the cylinder after engagement/disengagement motion. As the clutch is typically engaged for sustained periods of time, this prevents constant hydraulic pressure applied to the over-center mechanism and significantly reduces wear. Hydraulic/pneumatic hoses may pass through the housing and connect to engage and disengage bores of the cylinder via remotely actuated control valve(s). | 10-29-2015 |
| 192850550 | Details of master cylinder | 1 |
| 20160061276 | CLUTCH PEDAL SYSTEM AND MASTER CYLINDER FOR A CLUTCH PEDAL SYSTEM OF A VEHICLE - The clutch pedal system for a vehicle, such as a motor vehicle, is disclosed. The clutch pedal system includes a pedal carrier having a fastening region configured to be associated with an aperture in a bulkhead and/or a dashboard carrier of the vehicle. A clutch pedal is pivotably mounted on the pedal carrier. A master cylinder is supported on an adapter region of the pedal carrier and is connected to the clutch pedal. The master cylinder is positioned such that at least a portion of the master cylinder extends through the aperture, wherein the pedal carrier is configured to position the master cylinder in a predetermined position relative to the bulkhead and/or of the dashboard carrier. | 03-03-2016 |
| 192850570 | Fluid released clutch | 1 |
| 20140182994 | RELEASE DEVICE - A release device for a friction clutch, including an actuator for axially actuating the friction clutch, the actuator being designed to be hydraulically actuated by a fluid, and a support element having an integrated securing point for supporting the actuator on a clutch bell. An axial connection for the hydraulic fluid can be provided in the support element. The invention also relates to the possibility of designing the support element as a single piece with the housing of the actuator. | 07-03-2014 |

| 20140076681 | Slave Cylinder for a Vibration-Damped Hydraulic Force Transmission System, Particularly a Hydraulic Clutch Actuating System for Motor Vehicles - A slave cylinder for a vibration-damped hydraulic force transmission system, particularly a hydraulic clutch actuating system for motor vehicles is disclosed, comprising a cylinder housing, a piston received therein to be longitudinally displaceable and a pressure chamber which is bounded by the cylinder housing and the piston and which can be selectably acted on by a pressure medium, by way of a pressure connection provided in the cylinder housing, in order to displace the piston in the cylinder housing. An insert member which is inserted in the pressure chamber and secured in the pressure connection and which is equipped with a device for reducing pressure pulses, the device being constantly open to the pressure medium, is additionally provided. As a result, the vibration-damping measures or means are integrated in the slave cylinder in a particularly economic and space-saving manner. | 03-20-2014 |
| 20140166426 | WET FRICTION CLUTCH - A wet friction clutch comprising at least one clutch component which is rotatable around a shaft, wherein in the interior of the clutch component a rotary valve component that is rotatable around the shaft is formed which is deflectable by an angle of deflection in comparison to the rotatable clutch component by a relative rotation around the shaft, wherein the rotatable clutch component has at least one first opening and the rotary valve component has at least one second opening, wherein a total opening is released by an at least partial overlapping of the first opening and the second opening, the size of the total opening being dependent on the angle of deflection. | 06-19-2014 |
| 192850600 | Details of master cylinder | 1 |
| 20150300426 | CLUTCH HOUSING WITH INTEGRATED HYDRAULIC LINE - A clutch housing for a clutch assembly of a vehicle, the clutch housing comprising a fluid pathway at least partially disposed within a wall of the clutch housing, the fluid pathway forming at least a portion of a fluid line between a clutch slave cylinder and a clutch master cylinder, the fluid line being configured to transfer hydraulic fluid between the clutch slave cylinder and the clutch master cylinder. | 10-22-2015 |
