Abstract: A nozzle assembly includes a body, a valve member, and a clamp member maintaining a flow director member against the body. The flow director member is sandwiched between the peripheral wall and the clamp member, and is provided with an outlet path including two distinct guidance channels extending from an upstream end and a common downstream end where is a spray hole. The outlet path creates impingement of the two flow streams flowing in the two channels before entering the spray hole.

Abstract: An arrangement for supplying high pressure fuel to a plurality of fuel injectors includes a housing defining a fuel chamber. The chamber is provided with a flow inlet from a high pressure fuel source and forms a first portion of flow path of the fuel, the chamber being fluidly connected to a conduit providing a second portion of flow path. The conduit has a plurality of outlets adapted to provide flow of high pressure fuel from the chamber via the conduit to a corresponding plurality of injectors via respective first outlet flow conduits. The second portion of flow path is substantially narrower than the first flow path, and includes a pressure sensor located in or adjacent to the conduit.

Abstract: A nozzle assembly for an injection valve includes having a nozzle body recess and at least one injection opening, the nozzle body recess being hydraulically coupled to a high-pressure circuit of a fluid, and the injection opening being hydraulically coupled to the nozzle body recess. The nozzle assembly further includes at least one nozzle needle axially movable in the nozzle body recess, and having a central axis and a needle tip that interacts with a wall of the nozzle body recess such that in a closed position, the nozzle needle prevents a fluid flow through the injection opening(s), and in an open position, permits the fluid flow through the injection opening(s). Turbulence elements including recesses and/or protrusions formed as microstructures are arranged on the needle tip and/or walls of the nozzle body recess. The turbulence elements generate a predefined intensity of turbulence of the fluid in the injection opening(s).
