Relubrication distributors

With relubrication distributors the transportation of lubricant to the lubrication point only takes place during or after the relief process in the main line. This process therefore happens after switching off the lubrication unit. The achievable pressure in the circuit to the lubrication point is determined by the spring force and the piston surface. The pressure is lower than the maximum pressure of the prelubrication distributors. The relubrication thus has the function of a spring accumulator.
