The invention relates to turbocompressor construction, namely to devices for sealing systems for natural gas blowers.

The aim of the invention is to improve the operation efficiency by reducing the oil consumption at high pressure drops and reducing the dimensions.

In the drawing there is a float chamber, a slit.

A stand 2 with saddle 3 is mounted on the outlet nozzle 1. On the axis 4 in the rack there is a lever 5 with a float

connected to a shut-off organ, embodied in the form of a flat slide valve 7, blocking the hole 8 in the seat 3. A spring 9 is fixed on the rack 2, partially balancing the weight of the float 6. At the end of the discharge pipe 1 a ball valve 10 is installed, spring-loaded in the direction of opening with a spring 11 and fitted pusher 12, installed with the possibility of interaction with the lever 5 at low pressures.

The camera works as follows. In the presence of high pressure in the chamber chamber, the ball valve 10 is closed by differential pressure on. With an increase in the oil level, the float 6 is raised and by means of the lever 5 moves the flat spool 7. This opens the hole 8 in the saddle 3, and the oil is drained. Its consumption is minimal. Since only one valve is involved in the operation. The oil level is reduced, the float is lowered, the spool 7 covers the hole 8.

 low pressure in the chamber, which happens on the starting modes of the supercharger, and raising the oil level, which means that the float together with the flat slide valve 7 spring 1t opens and the ball valve tO.

Thus, at low pressure drops, both valves are involved in the oil drain, which provides the necessary flow rate at a small bore in the valve seat, allowing for a reduction in the level of permutation 5 forces, reducing the dimensions of the chamber elements and their mass. When the oil level decreases (no pressure), the ball valve 10 is closed by the float 6 by means of the lever 5 and the pusher 12, which eliminates the possibility of a breakthrough
