工作器械
摘要：
本发明涉及一种工作器械，其具有内燃机(12)，通过喷射阀(43)将燃料输送到该内燃机(12)处。内燃机(12)具有曲轴箱(16)，在曲轴箱(16)中可绕旋转轴线(17)旋转地支承有曲轴(26)。该工作器械具有用于输送用于内燃机(12)的冷却空气的风扇叶轮(39)，其布置在风扇罩壳(32)中。为了实现喷射阀(43)的良好的冷却，设置成，在风扇罩壳(32)中构造有连接孔(48)。喷射阀(43)布置在冷却区域(64)中，由风扇叶轮(39)输送的冷却空气通过连接孔(48)流入冷却区域(64)中。
摘要（英）：

The present invention relates to a work device which has an internal combustion engine (12) to which fuel is fed through an injection valve (43). The internal combustion engine (12) has a crankcase (16) in which a crankshaft (26) is rotatably supported about a rotation axis (17). The work device has a fan impeller (39) which is used for conveying cooling air for the internal combustion engine (12) and is arranged in a fan housing (32). In order to realize good cooling of the injection valve (43), a connecting hole (48) is formed in the fan housing (32). The injection valve (43) is arranged in a cooling area (64), and the cooling air conveyed by the fan impeller (39) flows into the cooling area (64) through the connecting hole (48).
