Abstract: A nozzle, comprising a housing; and an assembly including at least two deformable conjugated parts separated by a spacer seal, the assembly being arranged in the housing so as to form a nozzle outlet, the housing and the parts and the spacer seal being deformable so as to define a geometry of the nozzle outlet and seal surfaces between the parts and the spacer seal and between the parts and the housing; wherein the parts and the spacer seal are configured so that a force needed for inserting the assembly into the housing exceeds an assembly force that deforms of at least one of the housing and the assembly, and wherein the parts and the housing are deformed by the assembly force when assembled together to create a seal between the parts and the housing; and wherein the housing is fabricated from material having a lower hardness than the parts and the spacer seal.

Abstract: A nozzle having a housing and an assembly including at least two conjugated parts separated by a spacer seal. The assembly is arranged in the housing so as to form a nozzle outlet. At least one of he housing, the parts, and the spacer seal are deformable so as to define a geometry of the nozzle outlet and seal surfaces between the parts and the spacer seal and between the parts and the housing.

Abstract: A liquid fan jet nozzle having a housing with a central passage having an inlet and an outlet. A subnozzle is arranged in the central passage and has two round orifices arranged along converging axes so that round liquid jets exiting the round orifices collide at a distance from the orifices and form a fan-shaped jet.
