Accumulator – Alfa Romeo TCT
Accumulator – Alfa Romeo TCT

The accumulator is responsible to store the pressure of the hydraulic system for later access by the actuators. The bladder type accumulator has two cells: one cell storing the hydraulic fluid and one cell containing a gas to create counterpressure. Both cells are separated by a membrane. These accumulators have a certain life span and a common defect is that the gas leaks out of the cell, which causes the system to be unable to build up hydraulic pressure. In many of such cases, the pump appears to prime permanently.

The pump supplies the hydraulic pressure for the different consumers (actuators) of the Alfa Romeo TCT system and stores it in the pressure accumulator. The pump consists of a small gear pump and an electric motor. If the pump motor fails, the TCT cannot perform clutch operations or gear changes due to the lack of pressure.
