IPC8 Advanced - Invention: F15B11/00; F15B11/05; F15B13/04Title: CONTROLLER FOR HYDRAULIC MOTORAbstract:PURPOSE: To vary allowable pressure in a motor pipe in accordance with a working direction by providing a branch pipe furnished with one restriction and an overpressure valve on each of introduction parts and connecting the introduction parts to a remaining part of a load pressure pipe through a selector valve. CONSTITUTION: Two introduction parts 21, 22 are provided on a load pressure pipe 9. The introduction part 21 is connected to a load pressure sensing part 24 and the introduction part 22 is connected to a load pressure sensing part 23. The introduction part 21 is connected to an overpressure valve 29 through a branch pipe, and the introduction part 22 is connected to an overpressure valve 30 through the branch pipe, and restrictions 27, 28 are respectively provided on the introduction parts 21, 22.Consequently, as it is possible to adjust the overpressure valves 29, 30 respectively to different working values, it is possible to change working pressure in accordance with a working direction of a hydraulic motor 3.Applicant: DANFOSS ASInventor: TORUKIRUDO KURISUTENSEN;Inventor: HARII SUTENTOFUTO NITSUSEN;Inventor: KARUSUTEN KURISUTENSEN;Inventor: JIIKUFURIITO TSUENKERU;Inventor: SUBUENDO ERITSUKU TOMUSEN* * * * * *

IPC8 Advanced - Invention: F15B11/00; F15B11/05; F15B13/04Title: Dual load-sensing passage adjustable relief valves for hydraulic motor controlAbstract:There is provided control apparatus for controlling fluid flow between a bidirectional motor, a pump and a container, and includes a control valve that has a slide operative between neutral and first and second operative positions. A compensating valve is provided in the supply conduit that holds the upstream pressure drop at the control valve substantially constant and is controlled by load pressure sensing circuitry. The load pressure circuitry includes two branches that are connected through a change over valve to the compensating valve. There is provided an over pressure valve and a throttle point in each branch, each branch being connected to a load pressure sensing orifice of the control valve housing and fluidly connected through the slide to one of the housing motor orifices, the one depending upon whether the slide is in its first or in its second position.The circuitry permits the actuating pressure for operating the motor in one direction to be different from that for operating it in the other direction.Applicant: DANFOSS AS (DK)Inventor: CHRISTENSEN THORKILD (DK);Inventor: NISSEN HARRY S (DK);Inventor: CHRISTENSEN CARSTEN (DK);Inventor: ZENKER SIEGFRIED (DK);Inventor: THOMSEN SVEND E (DK)
