Nuova Tecnodelta manufactures hydraulic clutch pumps, hydraulic clutches/slave cylinders and concentric slave cylinders for vehicles and trucks.

When they first appeared on the French SIMCA 1000 in 1961, hydraulic clutch systems marked an important milestone for the automotive indus-try. The sensitivity and performance of the new system which provided almost optimal results, allowed for a smooth, gradually accelerating, and generally pleasant drive.

Since the frame was hydraulically linked to the gearbox by a flexible hose under pressure, the issue of unwanted vibrations did not even arise. Moreover, hydraulic clutch systems are de rigueur whenever the cable clutch alternative proves problematic. From a design standpoint, the clutch pump is very similar to a simple brake pump, generally without a bottom valve. The clutch cylinder resembles a blind brake cylinder (one-sided application with single piston) in the “standard” version or it includes a bearing in the “concentric” version which is fitted directly on the clutch mechanism.
