4. In the piston type sliding valve in the prior art, the piston is directly matched with the wall surface of the hole to realize fitting, but for a structure with limited size and volume, the piston rod and the piston structure are both longer, and the size control is influenced.
5. In the piston type slide valve in the prior art, the pistons are basically in a regular piston block structure, but the regular piston block is not flexible in plugging, space interference is easy to occur, and the manufacturing cost is high if the volume is large.
6. Although the inlet and outlet ports of the multi-way valve in the prior art can be used interchangeably in theory, the multi-way valve does not have a corresponding scheme for bidirectional use in practice, and when the multi-way valve is amplified into the whole oil way, the whole oil way structure cannot be reversible in the forward direction and the reverse direction.
7. In the piston type sliding valve in the prior art, the piston is probably provided with an internal passage, but the internal passage can only carry out one-way conveying, actually, a corresponding scheme for two-way use is not provided, and when the piston type sliding valve is amplified into the whole oil way, the whole oil way structure cannot be reciprocal in the forward direction and the reverse direction.
8. The piston and the piston rod in the prior art are provided with passages, but the technical scheme that the inlet and the outlet are arranged on the piston rod is not available.
