| description | The invention provides an oil nozzle structure and a throttle valve, and the oil nozzle structure comprises an oil nozzle body, a reinforcing pipe and a choked flow filtering part; the oil nozzle body is arranged in a throttling cavity of the throttling valve, one axial end of the oil nozzle body is communicated with a fluid inlet of the throttling cavity, and the other end of the oil nozzle body is communicated with a fluid outlet of the throttling cavity. A passing cavity is formed in the oil nozzle body; the reinforcing pipe penetrates through the oil nozzle body through the passing cavity; and the choked flow filtering part is arranged between the oil nozzle body and the fluid inlet of the throttling cavity, can buffer the fluid input into the throttling cavity and can also filter the fluid input into the throttling cavity. The integral structure of the oil nozzle body is reinforced through the reinforcing pipe, the oil nozzle body is prevented from being stabbed under the action of fluid turbulence, the |
