DEVICE FOR METERED FEED OF CONSISTENT LUBRICANT Russian patent published in 2001 - IPC

FIELD: delivery of consistent lubricants to friction units of machines by means of compressed air. SUBSTANCE: device has charging cylinder for lubricant and delivery cylinder whose rod-plunger is located in metering sleeve provided with inlet and outlet branch pipes; cavity of metering sleeve is communicated with under-piston cavity of charging cylinder through inlet branch pipe and check valve; charging and delivery cylinders are connected to actuating pneumatic system via distributor and check valves; delivery cylinder is located inside charging cylinder perpendicular relative to its longitudinal axis; metering sleeve is mounted in wall of charging cylinder by its outlet branch pipe for turn relative to rod-plunger locked against turn; wall of metering sleeve has through holes in section of initial contact with rod-plunger; these holes are located over helical line at preset pitch equal to pitch of turn of metering sleeve; end section of rod-plunger has longitudinal slot extending to its end face. EFFECT: possibility of setting required charges of lubricant. 3 cl; 5 dwg
