GETTER PUMP Russian patent published in 2018 - IPC F04B37/02 

FIELD: engines and pumps.

SUBSTANCE: invention relates to getter pumps used in pumping systems. Pump includes casing (21, 21'), having the shape of a body of revolution with axis of rotation (26), and a plurality of getter units (22, 23, 24, 25) installed inside said casing (21, 21'). Each getter unit (22, 23, 24, 25) comprises linear central supporting element (221, 231, 241, 251) and getter elements mounted at intervals on said linear central supporting element (221, 231, 241, 251). Plane orthogonal to axis of rotation (26) and intersecting the centre of the linear central supporting element (221, 231, 241, 251) forms mounting plane (222, 232, 242, 252) of the getter unit. Angles (α, α', α'', α'''), formed by said mounting planes (222, 232, 242, 252) and linear central supporting elements (221, 231, 241, 251) are in the range from 35° up to 75°.

EFFECT: pump can be used as an independent acting pump and also in pumping systems together with other types of vacuum pumps.
