Sliding vane type rotary piston

Abstract

The invention relates to a sliding vane type rotary piston. A crank connecting rod piston system is one of the most commonly used motion machines, has a complicated structure, and needs numerous parts such as a crank, a connecting rod and a reciprocating piston as well as a plurality of energy conversion links. As energy is consumed in each link, the total energy consumption is great. The sliding vane type rotary piston comprises a shell, a rotor, a sliding vane, an isolating block and the like, wherein the sliding vane on the rotor can slide relative to the rotor, the shell is divided into four parts, namely a high-pressure chamber, a piston chamber, a low-pressure chamber and a returning area, high-pressure fluid and low-pressure fluid are isolated from each other by the isolating block and at least one sliding vane of the piston chamber at any time, and the sliding vane retracts in or slides out at the high-pressure chamber or the low-pressure chamber. The sliding vane type rotary piston has the effect which is identical with that of the crank connecting rod piston system, and can be used in the occasions at which the crank connecting rod piston system can be used. The efficiency of the sliding vane type rotary piston is higher than that of the crank connecting rod piston system, and the sliding vane type rotary piston can be used in various occasions such as turbomachinery, engines and pumps and is very wide in application range.

[0002] The crank-connecting-rod-piston system is one of the most commonly used moving machines in modern industry. It is often used to convert fluid motion into mechanical rotation, or convert mechanical rotation into fluid motion. However, this mechanical structure is complex and requires a crank , connecting rod, reciprocating piston and many other components, there are many energy conversion links, because each link will lead to energy consumption, resulting in a large total energy loss

In order to improve efficiency, modern science and technology have developed many methods to replace the piston system. The common ones are: screw machine, diaphragm eccentric wheel rotary piston, etc., but these machines cannot completely replace the function of the crank-connecting rod-piston system, and the energy utilization efficiency is also low. not much improvement

[0003] In order to solve the problem that the efficiency of the piston system in the above-mentioned background technology is too low, the main reasons for the energy loss of the piston system have been carefully studied. Overcoming the inertia of the piston twice requires energy consumption, so in order to improve the efficiency of the piston system, the inertia of the piston must be eliminated. The present invention has carried out many improvements around how to eliminate the inertia consumption generated during the movement of the piston
