FIELD: railway transport. ^ SUBSTANCE: invention relates to devices for delivering lubricating material to wheel-rail friction surface. proposed device contains cylindrical housing open from one side and closed by cover from other side, cover being provided with hole. It has also sleeve coaxially fitted in housing and spring-loaded relative to housing and designed for accommodating lubricating rod, tubular member spring-loaded relative to housing, and guide. Tubular member is placed inside sleeve projecting beyond open edge of housing. One side of tubular member pointed to open part of housing is designed for engaging with lubricating rod, and other side of tubular member is connected with wire rope passing through hole in cover and connected by its other end with stop-holder. Stop-holder is arranged out of the housing to thrust against structural members of device at displacement of tubular member which is installed for displacement along inner surface of guide. ^ EFFECT: improved reliability of device and convenience in operation, simplified design, reduced overall dimensions. ^ 4 cl, 1 dwg |
