HYDRAULIC DISTRIBUTOR OF HYDRAULIC SYSTEM OF MOBILE MACHINE Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: hydraulic distributor had safety overflow section with an overflow valve, throttle-arrester of the flow in the control passageway and safety valve, working sections, each of which has housing with spaces of delivery, drain, consumers, and slide valve with grooves, radial and axial openings of the consumer flow, and device for connecting the control passageway to a consumer. The device is made so that the control passageway is interposed between the delivery space and the space of one of the consumers. The groove of the control passageway provided in the slide valve is coincident with the radial axial openings of the consumer flow. The groove of the control passageway in the slide valve is made so that its width is less than the diameter of the radial openings in the slide valve body. In addition the drain opening of the control valve may be interposed between the radial openings in the slide valve body. The supplying opening of the control passageway is coincident with the radial opening of the major flow in the slide valve. EFFECT: improved design. 3 cl, 5 dwg
