Brake valve latch with enhanced lubricity |
摘要 |
The present invention provides an improved lubrication system for use in a railway locomotive brake valve. Such railway locomotive brake valve includes a suppression cam having a plurality of detented control positions. It further includes a handle connected to the suppression cam for moving the suppression cam to such plurality of detented control positions. There is a spring loaded latch mechanism for engaging the suppression cam and providing a positive stop for such plurality of detented positions. The latch mechanism is a cylindrically shaped member with an elongated convex shaped protrusion at one end for engaging the suppression cam. Such brake valve further includes a bushing surrounding and guiding such latch mechanism. Such improved lubrication system comprises a coating of a preselected low friction material applied to and dried on at least one of the latch mechanism, the bushing and the suppression cam.
