Below only using by planet carrier as input element, sun gear as output element the space to form variable volume between ring gear and planet carrier, technical scheme is described.
Sun gear 1 is connected with the planetary gear 2 being arranged on planet carrier 3, and planetary gear 2 is connected with ring gear 4, ring gear 4 is also connected with one-way clutch 6, ring gear 4 is connected with class circle ring disk 7 by attachment screw 5, equipped with gear 19 on planet carrier 3, what be connected with gear 19 is three-apexed rotor 18, the inwall of three apexes contact class circle ring disks 7 of three-apexed rotor 18, the inwall of class circle ring disk 7 has special shape, can make three-apexed rotor 18 rotate process in all the time with the contact internal walls of class circle ring disk 7, a part for three-apexed rotor 18 and class circle ring disk 7 is between planet carrier 3 and base plate 10, so, three-apexed rotor 18, class circle ring disk 7, three spaces 17 are just constituted between planet carrier 3 and base plate 10, space 17 is by the fuel feed hole 21 on base plate 10, oil inlet pipe 20 or oil outlet 12, flowline 13 communicates with fluid reservoir 16, flowline 13 arranges valve 15, valve 15 is controlled its aperture by Valve controlling handle 14, base plate 10 is connected on class circle ring disk 7 by slide plate 8 and adjustment screw 9, base plate 10 is concentric with class circle ring disk 7 to be rotated to also have guide pin 11 to be made by the groove 22 on class circle ring disk 7 on base plate 10.
When planet carrier 3 rotates as input element, the gear 19 on planet carrier 3 can rotate together, and gear 19 drives three-apexed rotor 18 to rotate, and the volume of this time space 17 will change.
When valve 15 fully opens, the liquid in space 17 will be entered by fuel feed hole 21, oil inlet pipe 20, be discharged by oil outlet 12, flowline 13, and class circle ring disk 7 will remain stationary as under the combined effect of the resistance of motion and one-way clutch 6.
