| 摘要 |
The invention concerns a construction for controlled lubrication of one of a number of elements displaceable relative to one another by the movement of one of said elements. The proposed construction is used for lubrication to reduce wear and is applicable in numerous technical fields, for example craneways, elevator guide rails, cableways, and railways. The construction has a lubricant feeder (3) connected to the bore in one of the elements to be lubricated, advantageously in the stationary element, for example in the rail (1) - said bore being connected either directly or through a pressure pipe (7) to the surface exposed to the greatest wear - and to the lubricant container through a filling pipe (6). A cylinder connecting with a cavity provided with a suction valve (9) has a piston (11) which slides against a spring (17). A pressure body (14) which transmits the pressure of the moving element, for example the wheel (2), to the piston is provided. An element which modifies the movement of the pressure body (14), for example an adjusting screw (15), is provided and a pressure valve (10) is arranged in the pressure pipe (7) or in the space between the pressure pipe (7) and the cylinder. |
