Beschreibung
Zusammenfassung:	FIELD: mechanical vacuum pumps. SUBSTANCE: invention can be used for creating vacuum in milking plants. Proposed pump has rigid elliptical housing, fixed hub with suction and delivery spaces and working wheel. Cylinders with pistons are installed on external surface of housing at both ends of larger axis of ellipse. Pistons are spring-loaded from outer and inner surfaces and they divide cylinders into spaces. Spaces found from inner surface of piston are connected by channels with suction spaces of hub, and spaces located at outer surface of piston are in communication with atmosphere. Two elastic plates connected by rods with pistons of cylinders are installed inside housing square to larger axis of ellipse. EFFECT: reduced consumption of energy for building vacuum owing to automatic control of pump delivery depending on air flow rate. 1 dwg
