VACUUM PUMP AND ITS APPLICATION Russian patent published in 2012 - IPC F04B43/08 A61F2/78 A61F2/80 

FIELD: engines and pumps.

SUBSTANCE: in compliance with the first version, vacuum pump comprises compression elastomer element with internal reservoir containing fluid, discharge channel to communicate said internal reservoir and fluid receiver, and inlet channel to communicate internal reservoir and fluid source. Besides, said pump comprises first and second pressure elements jointed to elastomer element at opposite sides. At least, one of aforesaid pressure elements allows applying lengthwise force along said elastomer element and revolving force directed around the axis crossing compression elastomer element. Said first force makes fluid flow from internal reservoir into fluid receiver while said second force drives the fluid from fluid source into said internal reservoir. On applying second, revolving, force, elastomer element actuates despun force.

EFFECT: simplified design, improved operation.
