Fluid distribution

Abstract

The invention discloses a fluid distributor. The fluid distributor comprises a shell and a rotating shaft. A cylindrical hole is formed in the centre of the shell; a rotating shaft is arranged in the cylindrical hole, and is in close sliding fit with the cylindrical hole. A fluid inlet is formed in the shell, and is provided with a fluid inlet channel which is communicated with the cylindrical hole. A fluid outlet is formed in the shell, and is provided with a fluid outlet channel which is communicated with the cylindrical hole. The fluid inlet corresponds to the fluid outlet. A channel is formed in the rotating shaft; the rotating shaft rotates and / or moves axially in the shell; one end of the channel is aligned with the fluid inlet channel of the fluid inlet, and at the moment, the other end of the channel is aligned with the fluid outlet channel of the fluid outlet; the fluid inlet, the fluid inlet channel, the fluid outlet channel and the fluid outlet form a fluid passage. The rotating shaft rotates and / or moves axially in the shell, so that one end of the channel is deviated from the fluid inlet channel of the fluid inlet, and at the moment, the other end of the channel is also deviated from the fluid outlet channel of the fluid outlet; therefore, the fluid passage which is formed by the fluid inlet, the fluid inlet channel, the fluid outlet channel and the fluid outlet is closed.

Description

technical field [0001] The present invention relates to the field of machinery, and more particularly to machinery related to fluid flow and distribution. Background technique [0002] In mechanical equipment, a large amount of fluid flow and distribution are involved, especially in the fields of internal combustion engines, boilers and other thermal equipment, chemical equipment and other fields, which need to transport and dynamically and accurately distribute fluid fuels and raw materials. [0003] Take one of the most widely used diesel engines as an example. Diesel engines are the most widely used engines for heavy-duty vehicles, tractors, construction machinery, ships, and agricultural machinery. Diesel engines have the advantage of high power, but compared with clean and energy-saving fuels, they still have the disadvantages of high fuel consumption, low fuel efficiency, and serious emission pollution. Today, with the gradual reduction of fossil fuel resources and mo...

Problems solved by technology

From the working principle of the solenoid valve and the needle valve, it is easy to find that it takes a certain amount of time for the solenoid valve to drive the needle valve to open the oil circuit, or to drive the needle valve to reset and close the oil circuit by mechanical force.

In applications that require high-frequency opening and closing, the response time of the solenoid valve or spring itself is difficult to meet the requirements, and the high operating frequency will affect the service life and performance of the solenoid valve or spring

However, with the development of engine technology, the requirements for the engine will become higher and higher, which will also make the fluid distributor with solenoid valve and needle valve structure face more and more difficulties.
