摘要 |
<p>The invention relates to a pressure-regulating device for a hydraulic circuit comprising at least one generator (30) of pressurized fluid, a hydraulic motor (28) and a reservoir (32) of fluid under low pressure, and including an electrovalve controlled by a calculator and comprising, in a yoke (8), an electric coil (10) and a sliding magnetic core (12) controlling a slider (16) sliding in a bore provided in a body (18), the slider (16) defining two chambers (22, 36) arranged on either side of the slider (16) in the bore, the slider comprising a hydraulic enclosure (40) communicating with the hydraulic motor (28) and defining a reaction force supplementing the force generated by the coil (10), counter to a prestressed resilient mechanism (20), the enclosure (40) consisting of a blind bore made in the slider (16), a needle (42) closing the enclosure (40) in a substantially leaktight manner, while a radial pierced hole (44) connects it to a groove ( 34) provided at the periphery of the slider (16). According to the invention, the needle (42) bears on a cup (46) which is stationary with respect to the yoke (8) of the electric coil (10).</p> |
