Embodiment Construction

[0022] In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation mode combined with the accompanying drawings.

[0023] It can be seen from the accompanying drawings that this solution includes a pin sleeve and a valve casing fixed on the pin sleeve. A valve pin is arranged inside the pin sleeve, and an electric drive mechanism that can push the valve pin to move is arranged inside the valve casing. The electromagnetic drive mechanism includes There are inner yoke sleeve, electromagnetic solenoid and magnetic core; the magnetic core is set in the inner yoke sleeve, and the electromagnetic solenoid is wound outside the inner yoke sleeve; the magnetic core can move in the inner yoke sleeve, and the magnetic core can pass through the push rod Push the valve pin to move; there is an elastic reset mechanism between the magnetic core and the valve shell.

[0024] The elastic reset mechanism in this s...

Abstract

The invention provides an electromagnetic driver with elastic resetting mechanisms. According to the scheme, the electromagnetic driver comprises a pin sleeve and a valve outer shell fixed on the pin sleeve, valve pins are arranged in the pin sleeve, electrical driving mechanisms capable of pushing the valve pins to move are arranged in the valve outer shell, and each electrical driving mechanism comprises an inner yoke sleeve, an electromagnetic solenoid and a magnetic core, wherein the magnetic core is arranged in the inner yoke sleeve which is wound with the electromagnetic solenoid, the magnetic core can move in the inner yoke sleeve and push the corresponding valve pin to move through a push rod; the elastic resetting mechanisms are arranged between the magnetic cores and the valve outer shell. By means of the electromagnetic driver with the elastic resetting mechanisms, effective cushion protection can be conducted on resetting of the magnetic cores, and meanwhile the response speed of the magnetic cores can be increased.

Description

technical field [0001] The invention relates to an electromagnetic driver, especially an electromagnetic driver with an elastic reset mechanism. Background technique [0002] In the known electromagnetic driver, the magnetic core pushes the valve pin forward under the magnetic action of the electromagnetic solenoid, and the valve pin is acted by the return mechanism to push the magnetic core to reset. However, the electromagnetic driver of the existing electronic control system has the following defects: 1. There is no buffer protection for the return of the magnetic core, and it is impossible to avoid the hard contact between the magnetic core and the bottom plate of the valve shell; 2. The response of the magnetic core is only affected by the magnetic effect of the electromagnetic solenoid , the response speed has not been improved, which is a deficiency in the prior art. Contents of the invention [0003] The purpose of the present invention is to provide a technical s...
