A manual-transmission car generally adopts a system in which a brake pedal pressure is converted to a hydraulic pressure and a clutch body is controlled with the hydraulic pressure. Nabtesco Automotive provides clutch master cylinders and clutch operating cylinders for such system to automobile manufacturers.

By installing an Orifice valve along the clutch control line, it becomes possible to buffer the shock generated upon a sudden engagement of the clutch. Nabtesco Automotive orifice valve is provided with a feature for cancelling the orifice function when the operating temperature is low.
