Injection device for small power engine e.g. small internal combustion engine, of vehicle, has fuel pump, pressure regulator, injector and air controller arranged on common housing and formed as integral components of injection device

摘要

The device (2) has a fuel pump (20a), a pressure regulator (20b), an injector (20c) and an air controller (20d) arranged on a common housing and formed as integral components of the injection device. An actuator simultaneously actuates the pump and the air controller and is designed as a magnetic actuator with a coil (21) and an armature (22). The armature is designed as plunger piston with two end regions, which are respectively assigned to the fuel pump and the air controller. The fuel pump comprises a membrane (26) that is connected with one of the end regions of the plunger piston.
