A metering device is configured for fitting into a sand-spreading system of a rail vehicle. The metering device has a housing block, in which a sand path extends from a sand-feeding funnel into a vertical sand blow-out channel via a sand-mixing channel, which rises at an inclination from a sand-holding space to a sand deflection space. A pushing air tube is provided for producing an air flow that conveys spreading sand. The pushing air tube protrudes into the sand-mixing channel coaxially from the bottom. A nozzle insert is detachable inserted into an inflow channel, which leads into the sand deflection space from above. The nozzle insert is provided for producing an air jet directed downward into the sand blow-out channel. The amount of scattering sand that is discharged can be metered more precisely and the susceptibility of the metering device to wear is improved.

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.

A locomotive sanding system is described for conveying sand from a sand tower to a sand box mounted on a locomotive. The invention is designed to prevent personnel from being subjected to sand and sand dust during the sand box being filled with sand from the sand tower. The system includes a universal sealing nozzle which may be used with the locomotive sanding system or other devices. The universal sealing nozzle includes an expansion seal extending therearound which may be moved from a retracted position to an expanded position. When the nozzle is inserted into the fill pipe of the sand box, the expansion seal is expanded to sealably engage the inside surface of the fill pipe.

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.

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.

An anti-aquaplaning system for a motor vehicle includes: a storage unit for operating liquids, a mixing unit, a supply unit, and a dispensing unit. The dispensing unit includes at least a first injector and a second injector configured for the injection of liquid to the ground at the front of, respectively, a right tread and a left tread of a right wheel and a left wheel of a motor vehicle front axle. The anti-aquaplaning system operates with an operating mixture defined by operating fluids stored in a main tank and in at least one auxiliary tank.

A traction media is provided that includes a plurality of axes having a distal origin point and proximal point termination surrounded by one or more faces thus forming a body capable of being delivered by hand or traction enhancing system to a lower surface such as the ground to provide an increased coefficient of friction between an upper surface such as a shoe or tire and the lower surface and a relative air movement duct is provided that includes a controlled path of flow through about a 90 degree angle having an intake, discharge and baffle capable of delivering traction media from a hopper/valve assembly by an air flow to a lower surface such as the ground to provide a controlled path of traction media between an upper surface such as a tire and a lower surface such as the ground.
