摘要： A method for controlling a device for metering granular material and a metering device for metering granular material comprises a feed for the granular material from a container into a metering chamber. A metering piston can be actuated by a control device such that a gap between the feed and the metering chamber is opened by a predefined first distance and a second distance which is greater than the first distance. At least one sensor is arranged in a delivery line leading away from the metering chamber and is connected to the control device so that the metering piston can be actuated for a predefined duration such that the gap between the feed for the granular material and the metering chamber can be opened by the second distance if a blockage of the granular material is detected by the at least one sensor, so that the blockage is dispersed.

摘要： A device and method for dispensing a friction-coefficient-optimizing mixture of at least one lubricant and at least one grit into the gap between a rail wheel of a rail vehicle and a rail. The device includes a reservoir for the lubricant, a reservoir for the grit, a metering unit for metering the lubricant, a metering unit for metering the grit, a delivery apparatus for delivering the lubricant, a delivery apparatus for delivering the grit, and a common dispensing nozzle. The apparatus for delivering the lubricant and the apparatus for delivering the grit are separate from each other and end in the common dispensing nozzle, the friction-coefficient-optimizing mixture therefore not being formed until the dispensing, and an additional compressed air line is provided, which ends in the common dispensing nozzle.

摘要： The invention pertains to a discharge nozzle for discharging grit or lubricant into the gap between a rail and a track wheel of a rail vehicle, with the discharge nozzle comprising a base body with at least one connection for being connected to a conveyor line for the grit or lubricant and an outlet that is connected to the connection via a channel. In order to achieve an efficient and purposeful discharge of the majority of grit and/or lubricant into the gap between the rail and the track wheel, the outer contour of the base body is in the longitudinal direction shaped in a convex manner at least in the rear region lying opposite of the outlet and, if applicable, surrounded by an attachment such that the air flowing around the base body is accelerated in the direction of the outlet.

摘要： A metering device for granular material, includes a housing that can be arranged inside a container for the granular material. The housing has at least one inlet for the granular material and an outlet, which outlet can be closed by a sealing element. The sealing element is arranged on a metering piston, which is preloaded by a spring and can be moved axially in a compressed-air cylinder, wherein a compressed-air connection is provided on the compressed-air cylinder such that the metering piston can be moved against the spring by compressed air and the outlet can be opened, and the spring has an at least two-stage design such that the stroke of the metering piston can be changed at least in two stages by varying the compressed air.

摘要： 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.

摘要： A device for scattering grit in front of the wheels of a vehicle comprises a housing having a feed inlet for the grit, an outlet for the grit and a substantially cylindrical recess for receiving a brush roll which is rotatably mounted and driven about a substantially horizontal axis of rotation for the metered delivery of the grit from the feed inlet to the outlet. At least one wedge is arranged in the region of the feed inlet for the grit, in front of the brush roll and tangentially and displaceably with respect to the brush roll so that the size of the feed inlet can be adjusted.
