Electronic Clutch Actuator

Kinitics KPP Piston Pump as an electrohydraulic master cylinder for electronic clutch control

KPP05 Shape Memory Alloy Piston Pump

The Kinitics Piston Pump (KPP) is a shape memory alloy-based positive displacement pump that can be used an an electro-hydraulic master cylinder, offering the functionality of a motor, pump, and proportional valve in a single compact unit. Electrically powered, the KPP can be used to precisely control hydraulic devices, making it ideal for powertrain applications such as electronic clutch control.

High force, high speed, high precision: The KPP Piston Pump uses proprietary shape memory alloy technology to deliver a precise stroke in a compact package, enabling its use as an electro-hydraulic master cylinder.


No motors: The KPP electronic clutch actuator requires only AC or DC electrical power to operate; the only moving parts are the rod and piston for a compact size and excellent reliability.


Automated clutch control: The KPP Piston Pump can be inserted into an existing hydraulic system for electronic clutch control, yet manual clutch actuation can be retained by incorporating an isolation valve. Displacement or pressure control can be implemented when additional sensors are used.

The KPP Piston Pump can be used as an electronic clutch actuator in an automotive application, allowing automated clutch control in a small, lightweight unit. The technology has been used in the ShiftFX Electronic Shift Transmission(EST), a state-of-the-art transmission control system for OEM motorcycle applications. The system builds on existing gearbox design and enables push-button semi-automatic or fully automatic shifting.
