Abstract (en)
[origin: WO2016134397A1] The invention relates to a pneumatic pump device (100...105) for coupling to a container (2) for flowable material, comprising a jet pump (4) with at least one intake duct (7) extending away from the container (2) and leading into the jet pump (4) and an air supply duct (8) extending away from the container (2) and to which pressure can be applied or which leads to an outer surface of the pneumatic pump device (100...105). The at least one intake duct (7) and the at least one air supply duct (8) have essentially the same orientation in the region of the container (2) and are advantageously inclined relative to the vertical (z) by not more than 40°. The invention further relates to a metering system (110...116) comprising a container (2) and a pneumatic pump device (100...105) coupled thereto. The invention also relates to a use of the pneumatic pump device (100...105) or metering system (110...116) in a sanding system of a rail vehicle (28).
