Problems solved by technology
The multi-channel pulse digital stream obtained by using the cam rotor type pulse digital stream generating device can better solve the synchronous and asynchronous problems of multiple controlled objects when they work in parallel, but because the processing and production of the cam rotor is more troublesome, it makes the The manufacturing cost of the whole device is relatively high, and the production process is complicated, which brings some difficulties and inconvenience to practical application.

The invention relates to a piston reciprocating type pulse digital flow generation device used for fluid system digital control. The piston reciprocating type pulse digital flow generation device comprises a fluid pulse generator, the fluid pulse generator comprises two hydraulic cylinders, working pistons are arranged in the two hydraulic cylinders, and one side of each working piston is provided with a working oil port; plunger cavities communicated with corresponding one-way valve branches are further arranged in each hydraulic cylinder; a plunger used for forming a fluid pulse is arranged in each plunger cavity, and each plunger and the corresponding working oil port are arranged on the two sides of the corresponding working piston. The plungers are in transmission connection with the working pistons, and oil absorption and oil pressing motions are achieved under abutting driving of the working pistons conducting reciprocating motions so that the fluid pulses can be formed. As the plungers are only used as pulse generation elements, the functions owned by the working pistons and the plungers do not overlap any more, and influences of plunger end faces on effective pressure bearing areas of the working pistons are avoided. Meanwhile, all oil circuits of multiple paths of pulse digital flow are prevented from interfering with one another.
Description
technical field [0001] The invention relates to a piston reciprocating pulse digital flow generating device for realizing digital control of a fluid system in the technical field of fluid transmission and control. Background technique [0002] Fluid transmission and control technology is widely used in many fields of national economy. It is not only an effective transmission method, but also an important control method. With the increasing development and popularization of computer technology, it is an important trend in the development of fluid technology to use computers to carry out real-time digital control of fluid components and fluid power systems.
