Fuel pressure regulator

In Stock

If a high-performance motor is employed in a model helicopter - as is usually the case - it is normally virtually impossible to set up a regulated fuel supply. The Webra pressure regulator solves this problem by ensuring that the carburettor is fed an adequate quantity of fuel commensurate with any throttle barrel opening. This is achieved by pressurising the fueltank by means of a connection to the motor's crankcase (backplate). This means that fuel is supplied at adequate pressure to the pressure regulator, which in turn passes it on to the carburettor under regulated flow conditions. The pressure regulator itself is also connected to the silencer, and it is silencer pressure which controls the fuel regulation process, i.e. the quantity of fuel supplied to the carburettor varies according to motor speed: carburettor closed - less fuel; carburettor open - maximum fuel supply. The unit can be attached to the motor lugs using the mount supplied. The Webra fuel regulator is proof against methanol and easy to maintain. It is not suitable for petrol
