The invention relates to a device (1) for spreading granulate (2), in particular for spreading sand into the gap between rail (3) and wheel (4) of a rail vehicle (5), having a housing (6), having at least one inlet (7) for the granulate (2), and having at least one outlet (8) for the granulate (2), having an axially movable dosing piston (9), and having a compressed-air connection (11) which opensout in a pressure chamber (10) and which serves for the actuation of the dosing piston (9) by means of compressed air for the purposes of dosing the granulate (2), wherein at least one bore (14) is provided in the dosing piston (9). To create a device (1) which is of particularly simple and compact construction, a conveying air chamber (12) which is separate from the pressure chamber (10) and which has a compressed-air connection (13) is provided, and the at least one bore (14) in the dosing piston (9) connects the conveying air chamber (12) to the at least one outlet (8) for the granulate (2), such that the granulate (2) can be conveyed to the at least one outlet (8) independently of the dosing by means of compressed air.

    本发明涉及一种用于散布颗粒(2),特别是用于将沙子散布到导轨(3)和轨道车辆(5)的轮(4)之间的间隙中的装置(1),其中所述装置包括壳体(6),用于颗粒(2)的至少一个入口(7)和用于颗粒(2)的至少一个出口(8),可轴向移动的计量活塞(9)和压缩空气连接部(11),所述压缩空气连接部通向压力室(10)并用于借助于压缩空气致动所述计量活塞(9)以便计量颗粒(2),并且其中至少一个腔孔(14)设置在所述计量活塞(9)中。为了创造特别简单且紧凑构造的装置(1),提供与所述压力室(10)分离并且具有压缩空气连接部(13)的输送空气室(12),并且所述计量活塞(9)中的所述至少一个腔孔(14)将所述输送空气室(12)连接到所述用于颗粒(2)的至少一个出口(8),使得可以独立于计量过程借助于压缩空气将颗粒(2)输送到所述至少一个出口(8)。
