A pneumatic pump device coupled to a container for flowable material includes a jet pump with at least one intake duct extending away from the container and leading into the jet pump and an air supply duct extending away from the container and to which pressure can be applied or which leads to an outer surface of the pneumatic pump device. The intake duct and air supply duct have essentially the same orientation in the region of the container and are advantageously inclined relative to the vertical by not more than 40&#xb0;. A metering system includes a container and such a pneumatic pump device coupled thereto and the use of the pneumatic pump device or metering system in a sanding system of a rail vehicle.

Pneumatic pump device and metering system and sanding system, comprising a jet pump for flowable material

A sanding system for a rail vehicle includes a housing of a cellular wheel sluice having an inlet located at the top and an outlet located at the bottom, a pivotably mounted cellular wheel having a plurality of cells, and a motor that is coupled with the cellular wheel. The sanding system further includes a container connected to the inlet of the cellular wheel sluice for receiving brake sand, or a feed line connected to the inlet of the cellular wheel sluice for transporting brake sand, and a discharge line connected to the outlet of the cellular wheel sluice for transporting brake sand. The motor for driving the cellular wheel is thereby arranged above the inlet.

Sanding system comprising a protected motor

The present invention relates to a sand dispenser for a rail vehicle, wherein the sand dispenser comprises a metering device, a delivery device and an uncoupling device. The metering device is designed to pneumatically meter a desired quantity of sand using a metering air flow. The delivery device is designed to pneumatically deliver the quantity of sand to at least one scattering site using a delivery air flow. The uncoupling device is designed to pneumatically uncouple the metering device and the delivery device, wherein the uncoupling device is designed to provide a compensating air flow for compensating a difference between an output air flow of the metering device and an input air flow of the delivery device.
