<p>1. Control device for a centralised lubrication installation, comprising a feed pump directly or indirectly electrically controlled (+E) and intermittently with predetermined intervals of time, and an electronic numerical counter (CO) comprising an input for resetting to zero (Z) and a principal output (B) which becomes active at the end of a determined time, preferably controllable, this control device comprising a lubricating flip-flop (B2) whose control input (S) is actuated by the said output (B) of the counter (CO), whose input for resetting to zero (R) is actuated by an input (+P) connected to a system (P) for lubrication control, and whose output (Q) actuates, on the one hand, the input for resetting to zero (Z) of the counter (CO), and on the other hand, the control output (+E) of the pump or of the solenoid valve (EV) for actuating the pump, by the intermediary of an amplification circuit (T, Br, Cr), characterised by the fact that it comprises an additional cycle control (M) actuating (m) the control input (S) of the lubricating flip-flop (B2) in parallel with the control (b) issuing from the counter (CO), by the intermediary of a logic "OR" gate (OR), and by the fact that the control system is a manostat controlling the establishment of the pressure at the end of the lubricating line.</p> |
