HYDRAULIC DISTRIBUTOR FOR MECHANIZED WORKS Russian patent published in 1995 - IPC

FIELD: hydraulic engineering. SUBSTANCE: housing is coupled with a base having supplying and discharging branch pipes. A rotatable slide, having bores coupled with each other trough passages, is received in the. One of the bores is arranged for communication with the discharging passages. The other bore is in constant communication with the supplying passage. A check valve is received in the bore. The check valve has spring- loaded hollow plunger, pusher with the shank, bushing, and cover. A control handle is mounted on the rotatable slide for interaction with the shank. The supplying passage is in communication with the passage of the slide through a check valve. The slide passage is connected to the first bore. The second bore is made in the slide and has eccentricity with respect to its rotation axis. The slide is provided with inlet bushing mounted in the second bore. The check valve is in communication with the supplying passage through the inlet bushing. EFFECT: improved design. 4 cl, 3 dwg
