HYDRAULIC REDUCTION VALVE |
摘要 |
FIELD: machine building.SUBSTANCE: hydraulic reduction valve comprises a body. It contains a spring-loaded cylindrical slide valve with throttling slots on slide valve collars, a channel of drain into an under-end cavity of the slide valve at the side of a spring, a discharge channel into a collar-to-collar cavity of the slide valve and a channel of reduced pressure from a cavity at the side of the free end of the slide valve. In the cylindrical slide valve there is a central hole at the side of the free end connected with a bore on the slide valve collar on the side of the spring-loaded end. The bore on the collar may connect via throttling slots on the collar with the drain channel.EFFECT: valve may stabilise pressure in a reduced cavity, controlling its flow by its redistribution through throttling slots on a slide valve into a drain cavity.2 dwg |
