Abstract

The invention discloses a valve rod matching high-pressure common-rail oil atomizer which comprises a valve rod matching high-pressure common-rail oil atomizer body. A mounting head is connected to the outer side of the valve rod matching high-pressure common-rail oil atomizer body, a supporting mechanism is arranged on the outer side of the valve rod matching high-pressure common-rail oil atomizer body, and a connector is connected to the outer side of the valve rod matching high-pressure common-rail oil injector body. According to the valve rod matching high-pressure common-rail oil atomizer, through the arrangement of the supporting mechanism, supporting of a groove in the outer side of the valve rod matching high-pressure common-rail oil atomizer body can be enhanced, a shell of the valve rod matching high-pressure common-rail oil atomizer body is evenly stressed, and the problems that deformation is prone to happening and the service life is affected are solved; and through the arrangement of a reinforcing mechanism, the outer side of the valve rod matching high-pressure common-rail oil atomizer body can be protected through a reinforcing sleeve, and the service life of the valve rod matching high-pressure common-rail oil atomizer body can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of high-pressure common-rail fuel injectors, and in particular relates to a high-pressure common-rail fuel injector with coupled valve stems. Background technique [0002] The high-pressure common rail injector includes the characteristics of a conventional injector, and also includes an injector that uses an electromagnetic control valve to control the injection start and end device, and the valve stem and the high-pressure common rail injector are precisely coupled. Clearance fit structure, when the fit gap between the valve stem and the valve stem sleeve is out of tolerance due to wear, the valve stem sleeve and valve stem can be replaced directly, which reduces the maintenance cost of the high-pressure common rail injector. The existing valve stem coupler During the use of componentized high-pressure common rail injectors, the groove of the shell is under relatively large pressure, which is easy to defor...
