Internal Combustion Engine Having an Elastic Connecting Duct
First Claim
1. An internal combustion engine of a manually operated implement, wherein said engine has an inlet for the supply of fuel/air mixture and an air duct window, comprising:
- an elastic connecting duct disposed between said internal combustion engine and an air filter for vibration-decoupled bridging of a vibration gap between said engine and the air filter, said elastic connecting duct having a first conduit for fuel/air mixture, wherein said first conduit has a bore extending from a first end to a second end of said first conduit, and a second conduit for largely fuel-free air, wherein said second conduit has a bore extending from a first end to a second end of said second conduit, wherein said first conduit and said second conduit are embodied as separate tubes, wherein said bore in said first conduit and said bore in said second conduit are separated from one another over their entire lengths, wherein said inlet of said engine is operatively connected to the air filter via said first conduit, and wherein said air duct window is operatively connected to the air filter via said second conduit.

Abstract
An internal combustion engine of a manually operated implement, having an elastic connecting duct between the engine and an air filter for vibration-decoupled bridging of a vibration gap between engine and the air filter. The elastic connecting duct has a first conduit for fuel/air mixture and a second conduit for largely fuel-free air. The first and second conduits are separate tubes having respective bores that are separated from one another over their entire lengths, the inlet of the engine is operatively connected to the air filter via the first conduit, and an air duct window of the engine is operatively connected to the air filter via the second conduit.
