Device for storage and feed of volatile fuel components into IC engine - has return valve with flow intake and outlets, with one elastomeric seal actuated by differential pressure

摘要

The IC engine (5) is actuated by a supercharger (15). The valve outlet (14) is connected to a return valve (16) in direction of the intake tube (4). The valve has housing (17) with flow intake (18) and two outlets (19,20). One outlet is connected to the low pressure section of the supercharger, the other is connected to the intake tube. The outlets have a common seal body (21) of elastomeric material, which is actuated by differential pressure. The part of the seal body associated with one outlet has flow in direction of the supercharger only, the other has flow in direction of the intake tube only. USE/ADVANTAGE - For temporary storage and dosed feed of fuel. Simple and economical manufacture, compact dimensions, long life time.
