| description | The utility model comprises a transmission shaft 5 which is driven to rotate by a plunger piston cylinder. The different homocentric circumferences of the plunger piston cylinder are provided with a plurality of groups of plunger piston holes and a plunger piston 10. The utility model is characterized in that each group of plunger piston bores have a plurality of pairs of plunger piston bores. Each pair of plunger piston bores are respectively connected with a distributing groove or a distributing ring, and the plunger piston bores compose an independent entering and returning oil circuit via an external connection oil circuit and a Y typed control valve. The pairs of the plunger piston on the same circumference are selectively driven to work entirely or partly according to the requirement of the speed regulation, which can reach step or stepless variant. The utility model having the characteristics of simple structure, cabinet volume and convenient installation and arrangement can be used on automobiles, especially cars. Because of using the electrohydraulics servo control system, the utility model can be conveniently butt jointed with computers. |
