Scattering device for vehicle i.e. rail vehicle, to dose sand amount from sand container, has sand conveying system working according to injector principle, and nozzle connected upstream to injector in pressurized air conduit
The device has a sand conveying system controlled by pressurized air and working according to an injector principle. A nozzle (12) is connected upstream to an injector (3) in the pressurized air conduit. The nozzle is provided in the pressurized air conduit between a non-return valve (11) and the injector. The control device comprises a bucket wheel sand dosing and closing unit (2), which is driven by a radial piston motor (14). A motor speed control comprises a throttle valve, which is directly provided on the pressurized air conduit.
