US 2016/0244074 A1 · SAND DISPENSER FOR A RAIL VEHICLE AND METHOD FOR PROVIDING SAND FOR A RAIL VEHICLE

Abstract

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.

Dependent claims

A sand dispenser for a rail vehicle, the sand dispenser comprising:

a metering device for pneumatically metering a desired sand quantity using a metering air flow;
a conveying device for pneumatically conveying the sand quantity to at least one scattering location using a conveying air flow;
and
a decoupling device for pneumatically decoupling the metering device and the conveying device,
wherein the decoupling device is constructed to provide a compensation air flow for compensating for a difference between an outlet air flow of the metering device and an inlet air flow of the conveying device.
