The second connection (44) for the other conduit (12, 14) is located on the side of the fourth shut-off device (38) facing away from the second leakage chamber (42).

It does not leak out of the tent room.

A shaft seal (14) is arranged on the oil pump side next to the leakage collecting space (12), and in the leakage collecting space (12) a leakage pump (15) is arranged on the drive shaft (3).

If no internal leakage is detected, each chamber is then tested with respect to a possible external leakage.

Hence, a chance of leakage of the fluid media from the chamber is reduced.

An o-ring located on the posterior chamber is used to prevent leaks.

Filtered blow-by gas may also be introduced into the combustion chamber.

The negative internal air pressure acts to facilitate sealing the chamber to prevent escape of substantially all airborne infectious particles from the chamber.

Accordingly, the leakage of the fuel oil from the combustor (1) can be accurately detected.

The correction/control is performed when the leak detection device detects the leakage of gas from the gas spring into the combustion chamber.

An o-ring is also located between the glass window and the chamber to prevent leaks.

According to the invention, the additional bore is a leakage receiving bore (4) or a noise reducing chamber (12).

A control valve (58) is arranged in the housing (1), by which means the control chamber (50) can be connected to a leak oil chamber (78).

A leakage connection is formed between the valve chamber (40) and the low pressure chamber (36) when the valve seat (18) is closed, which connection enables a diverting of the leak from the valve chamber (40) into the low pressure chamber (36).
