Abstract

See full text

A device for spreading granulate, particularly for spreading sand into the gap between a rail and a wheel of a rail vehicle, includes a housing, at least one inlet for the granulate and at least one outlet for the granulate, an axially movable metering piston and a compressed air connection, which leads into a pressure chamber and serves for actuating the metering piston by compressed air to meter the granulate. At least one bore is provided in the metering piston. To create a device which is of particularly simple and compact construction, a conveying air chamber separated from the pressure chamber and has a compressed air connection is provided, and at least one bore in the metering piston connects the conveying air chamber to the at least one outlet for the granulate, such that granulate can be conveyed to the at least one outlet by compressed air independently of the metering process.
