Abstract
An inlet body is for a fluid injector for a turbomachine. The inlet body includes a casing and an inlet nozzle, housed inside the casing, that serves as a seat for a mobile sealing member. The inlet nozzle includes a central duct for the fluid and an annular rim surrounding the central duct. The annular rim includes a housing for a gasket. The housing is defined by a bottom wall, an opening opposite the bottom wall, and two opposite walls which each extend between the bottom wall and the opening. The walls are tilted towards each other in the direction of the opening.

An inlet body for injecting fluid for a turbomachine, comprising:
- a casing;
- and
- an inlet nozzle which is housed inside the casing and which is configured to be used as a seat for a mobile stopper, wherein the inlet nozzle comprises:
- a central pipe for the fluid, and
- an annular rim surrounding the central pipe and wherein the annular rim comprises a housing for a gasket,
- wherein the housing is delimited by a base wall, an opening opposite the base wall, and two opposite walls which each extend between the base wall and the opening,
- wherein the gasket is crimped into the housing by the walls which are inclined towards one another in the direction of the opening, and
- wherein the annular rim comprises an evacuation pipe opening into the housing and to the exterior of the inlet nozzle, wherein the evacuation pipe is configured to evacuate fluid out of the housing.
A method for the production of an inlet body, wherein the inlet body comprises:
- a casing;
- and
- an inlet nozzle which is housed inside the casing and which is configured to be used as a seat for a mobile stopper, wherein the inlet nozzle comprises:
- a central pipe for the fluid, and
- an annular rim surrounding the central pipe and wherein the annular rim comprises a housing for a gasket,
- wherein the housing is delimited by a base wall, an opening opposite the base wall, and two opposite walls which each extend between the base wall and the opening,
- wherein the gasket is crimped into the housing by the walls which are inclined towards one another in the direction of the opening,
- wherein the annular rim comprises an evacuation pipe opening into the housing and to the exterior of the inlet nozzle, wherein the evacuation pipe is configured to evacuate fluid out of the housing, and
- wherein the method for the production of the inlet body comprises:
- inserting the gasket into the housing;
- and
- deforming the housing so as to incline the walls relative to one another in the direction of the opening.
