Definitions

• a combustible adsorbent pump (sv, ⁇ , 1333833) is known to contain a discharging element, consisting of a liquid nitrogen vessel, which is a dry source of oil
• the indicated areas of the facilities are ringed. Foreign spaces between adjacent sewers and open screens are communicated from the input of the pump.
• the vessel for the agent has a ring guard with two tubes for entering the vessel of the agent and the pumping unit. These tubes are attached to the upper end of the casing.

• the pumping element is shipped with a radiating shielding to reduce thermal radiation from the emergency housing I.
• the shielded vessels are equipped with a 15-port safety vessel.
• an additional screen 31 has been installed, which is designed to reduce the thermal radiation of the radiation from the housing I ⁇ radiation.
• Chevron screens in the vacuum - 6 - shoved volume sends a double-sided display in the form of a thick aluminum layer with a thickness of at least 1 ⁇ m and an aluminum oxide layer with a thickness of 2 to 20 nm.
• the local screens 17 and 26 have a space of 5 at least 150 ⁇ m with a gradual frequency not lower than 0.99 in a range of lengths of 2-200 ⁇ m.
• the proposed pump operates as follows. ⁇ In the input unit 3, it is not immediately available or after a shutter (not shown) it connects the pumped working chamber (not shown).
• 28 Inlet 28 is disconnected through a valve (not shown) with a metallic seal inlet (not indicated) and not supplied with pressure Then after one of the branches 32 through the valve (not shown)
• the vessel 15 of the radiation screen in the case of the 18th tank is filled with a liquid agent, for example, liquid nitrogen.
• a liquid agent for example, liquid nitrogen.
• 25 pipe 13 is filled with a liquid agent that has a temperature lower than that of a vessel in vessel 15; ⁇ In the latter case, a decrease in the temperature of the agent in the vessel 4 is achieved by pumping it out with the vacuum mechanical mechanism.
• the accessories located in the rings of the 10 exhausting element.
• the absorber absorbs gases from the working chamber, ensuring that the pressure is prevented by - 7 - 10 Pa and below.
• the 4 diameter of the pipe 13 may be increased correspondingly.
