Abstract
In a central lubricating installation which is primarily intended for commercial vehicles the running time of the pump unit (2) supplying lubricant to the lubricant distributors (6, 7) is controlled as a function of the ambient temperature, determined by means of a temperature sensor (23).
Claims10
Central lubricating installation, in particular for commercial vehicles, comprising a lubricant reservoir (1), a pump unit (2) , a control device (15) controlling interval and running times of the pump unit (2), a pressure sensor (22) interacting with the control device (15) and monitoring the satisfactory operation of the installation, a pressure limiting valve (14), and also lubricant lines (5) through which lubricating grease can be delivered to lubricant distributors (6, 7) allocated to lubricating points (8-13) which are at different distances from the pump unit, characterized in that an ambient temperature sensor (23) is allocated to the control device (15), signals of which the ambient temperature sensor are used to change the running time of the pump unit (2) as a function of ambient temperature and of penetration behaviour of the lubricating grease by decreasing the running time as the ambient temperature increases.
