    摘要： The invention relates to a carburetor arrangement for an internal combustion engine (1) which drives a work apparatus. The engine (1) has an intake channel (3) leading through a carburetor (2). The intake channel (3) includes an intake opening (4) on the side of the carburetor (2) facing away from the engine (1). A baffle wall (5) is provided and covers the intake opening (4) at least partially. The baffle wall (5) is mounted transversely to the longitudinal axis (6) of the intake channel (3) at a spacing to the intake opening (4). The baffle wall (5) and the intake opening (4) define a baffle enclosure (7) disposed therebetween. At least a first component part (8) of the baffle wall (5) is inclined with respect to the longitudinal axis (6) of the intake channel (3) in such a manner that fuel droplets (9), which exit from the intake channel (3) and which impinge on the first component part (8) of the baffle wall (5), form a fuel film (10).

    摘要： The invention is directed to a membrane carburetor for changing the air/fuel ratio. The membrane carburetor achieves the same result as previous carburetors but at a greater insensitivity to wear and disturbances as well as an improved controllability in a constructively simpler and more compact manner. The carburetor includes a coil arranged about a valve needle so that the coil and the valve needle conjointly define a solenoid actuator. The valve needle is the armature of the solenoid actuator. When a limit rpm is reached, the coil is activated by a current and the armature is raised and thereby a greater flow of fuel is made possible. The enrichment of the air/fuel mixture achieved in this manner limits the engine rpm. The membrane carburetor wherein the air/fuel ratio can be changed is for an internal combustion engine of a portable handheld apparatus such as a motor-driven chain saw, hedge clippers and the like.

    摘要翻译： 本发明涉及一种用于改变空气/燃料比的膜式化油器。 膜化油器实现与以前的化油器相同的结果，但是对于磨损和干扰更大的不敏感性以及以更简单和更紧凑的方式改进的可控性。 化油器包括围绕阀针布置的线圈，使得线圈和阀针联合地限定螺线管致动器。 阀针是螺线管执行器的电枢。 当达到极限转速时，线圈被电流激活，并且电枢升高，从而使得更大的燃料流成为可能。 以这种方式实现的空气/燃料混合物的富集限制了发动机转速。 其中可以改变空气/燃料比的膜式化油器是用于诸如电动链锯，树篱剪等的便携式手持装置的内燃机。
