| description | The present application relates to the technical field of injectors. Disclosed is a variable thrust pintle type injector, which aims to solve the problems of a complex structure and low operating reliability of an injector due to strict operating environment conditions required for mechanical actuation regulation. The variable thrust pintle type injector comprises a housing, a central cylinder, and a pintle. The housing has a first through cavity, wherein a first flow channel for introducing a first propellant is formed in the housing, and the first flow channel is in communication with the first cavity. The central cylinder is nested in the first cavity and has a second cavity for introducing a second propellant, and a second flow channel is provided in an end of the central cylinder close to a combustion chamber. The pintle is arranged between the central cylinder and the housing, and a third flow channel is formed between an inner wall of the housing and an outer wall of the pintle. When the pintle moves i |
