As shown in Figure 1, 2, 3, the single-acting blade secondary component of a kind of Non-follow control described in the utility model is mainly adjusted screw 18 by housing 1, left end cap 2, rotating shaft 3, valve plate 4,12 and stator 5, rotor 6, blade 7, upper end cover 8, top board 9, roller 10, lower platen 11, right end cap 16, left cover 17, pretightning force, bias adjusts screw 26 and nut 19,25 and spring base 20, preloading spring 21, slide 22, variable piston 24, right cover plate 27, clapboard 28 etc. form；The center of rotor 6 is fixing, the center of stator 5 can be moved to the left or to the right, the center of stator 5 can be in left side or the right side at rotor 6 center, the width of the width ratio stator 5 of rotor 6 is slightly smaller, rotor 6 is arranged in stator 5, the blade groove of rotor 6 is put in one end of blade 7, the other end contacts with the inner surface of stator 5, blade 7 radially disposes (namely laying angle is zero) along rotor 6, rotor 6 coordinates connection with rotating shaft 3 by flat key, under the effect of constant pressure network system mesohigh oil, rotor 6 can be rotated axle 3 and rotate；nullThe left end of variable piston 24 contacts with the right surface of stator 5，The right-hand member of variable piston 24 contacts with the eccentric left end head adjusting screw 26，Variable piston 24 is installed within the case 1，The eccentric screw 26 that adjusts is arranged in right cover plate 27，And be fastened on right cover plate 27 by nut 25，Right cover plate 27 is arranged on housing 1 by bolt，Adjusting screw 26 by rotating eccentricity can drive variable piston 24 to move left and right，The right-hand member of slide 22 contacts with the left surface of stator 5，Slide 22 is installed within the case 1，One end of preloading spring 21 is put in slide 22，The other end of preloading spring 21 is placed on spring base 20，The right end that spring base 20 adjusts screw 18 with pretightning force contacts，Pretightning force adjusts screw 18 and is arranged in left cover 17，And be fastened on left cover 17 by nut 19，Left cover 17 is arranged on housing 1 by bolt，The pretightning force of screw 18 adjustable preloading spring 21 is adjusted by rotating pretightning force，When not working，The center superposition (this position is called initial position) of the center of rotor 6 and stator 5，Now preloading spring 21 has a certain size pretightning force，During work，Eccentric adjustment screw 26 clockwise or counterclockwise，Variable piston 24 can be driven to move to the left or to the right，Thus driving stator 5 to move to the left or to the right，The size and Orientation changing rotor 6 and stator 5 eccentric throw realizes variable；Upper end cover 8 is bolted on housing 1, top board 9 passes through bolt-connection on upper end cover 8, lower platen 11 contacts with the outer surface cooperation of stator 5, roller 10 is arranged between top board 9 and lower platen 11, roller 10 contacts with the lower surface of top board 9 and the upper surface cooperation of lower platen 11, lower platen 11 can move left and right with stator 5, and valve plate 4,12 is arranged on rotating shaft 3, and is pressed on the side, two, left and right of stator 5.The oil inlet and outlet size of secondary component is identical.

When secondary component does not work, the center superposition of the center of stator 5 and rotor 6, eccentric throw is zero, and the discharge capacity of secondary component is zero, and this position is the initial position of secondary component, i.e. zero point.

During secondary component work, unclamping nut 25, rotating eccentricity counterclockwise adjusts screw 26, variable piston 24 moves right, stator 5 center is on the right side at rotor 6 center, and the center of the center of stator 5 and rotor 6 just creates an eccentric throw, regulates and terminates rear fastening nut 25.When hydraulic fluid port oil-feed on secondary component, during lower hydraulic fluid port oil return, hydraulic fluid port oil inlet end on the secondary component shown in Fig. 3 (a), in the closed area being made up of rotor 6, stator 5, two adjacent blades and left and right valve plate 4,12, owing to the compression area of right side blade is more than the compression area of left side blade, under the effect of pressure differential, rotor 6 and power transmission shaft 3 (direction facing to secondary component power transmission shaft 3) in a clockwise direction rotate, secondary component works with " hydraulic motor " operating mode, consume the energy of hydraulic system, drive loaded work piece.

If stopping to secondary component fuel feeding, under load inertia kinetic energy effect, rotor 6 and power transmission shaft 3 continue in a clockwise direction (direction facing to secondary component power transmission shaft 3) and rotate, now, unclamping nut 25, turn clockwise eccentric adjustment screw 26, and variable piston 24 is moved to the left, make stator 5 center in the left side (zero crossing) at rotor 6 center, regulate and terminate rear fastening nut 25.In Fig. 3 (b), the closed area volume that under secondary component, oil port is made up of rotor 6, stator 5, two adjacent blades and left and right valve plate 4,12 constantly increases, and produces vacuum, sucks fluid, and lower hydraulic fluid port just becomes inlet port；The closed area volume that upper oil port is made up of rotor 6, stator 5, two adjacent blades and left and right valve plate 4,12 constantly reduces, fluid is forced out in entrance hydraulic system through upper hydraulic fluid port, work with " hydraulic pump " operating mode, to hydraulic system feedback energy, and play braking action.

If the center of stator 5 is in the left side at rotor 6 center, to the logical pressure oil of hydraulic fluid port on secondary component, during lower hydraulic fluid port oil return, the oil inlet end of hydraulic fluid port on the secondary component shown in Fig. 3 (c), by rotor 6, stator 5, two adjacent blades and a left side, right valve plate 4, in the closed area of 12 compositions, owing to the compression area of left side blade is more than the compression area of right side blade, under the effect of pressure differential, rotor 6 and power transmission shaft 3 (direction facing to secondary component power transmission shaft 3) in a counterclockwise direction rotate, secondary component works with " hydraulic motor " operating mode again, consume the energy of hydraulic system, drive loaded work piece.

Unclamp nut 25, rotating eccentricity counterclockwise adjusts screw 26, variable piston 24 moves right, effect by variable piston 24, the center of secondary component stator 5 is adjusted to the right side (zero crossing) at rotor 6 center, adjustment terminates rear fastening nut 25, and stop to secondary component fuel feeding, if rotor 6 and power transmission shaft 3 (direction facing to secondary component power transmission shaft 3) still in a counterclockwise direction rotate, now, in Fig. 3 (d), under secondary component, oil port is by rotor 6, stator 5, two adjacent blades and a left side, right valve plate 4, the closed area volume of 12 compositions constantly increases, produce vacuum, suck fluid, lower hydraulic fluid port just becomes inlet port；The closed area volume that upper oil port is made up of rotor 6, stator 5, two adjacent blades and left and right valve plate 4,12 constantly reduces, fluid is forced out in entrance hydraulic system through upper hydraulic fluid port, work with " hydraulic pump " operating mode, to hydraulic system feedback energy, and play braking action.

The size and Orientation of rotor 6 and stator 5 eccentric throw is determined by the displacement of variable piston 24, and the displacement of variable piston 24 is adjusted the controlling angle of screw 26 by bias, is adjusted the displacement (size and Orientation) of screw 26 adjustable variables plunger 24 by rotating eccentricity.
