Automatic lubrication system

摘要

The system includes a series of divider valves operable periodically through a cycle in which charges of lubricant are delivered one after another in sequence to a number of points of lubrication. The valves are supplied with lubricant from a reservoir holding a supply of lubricant under pressure via an on-off control valve, the latter being controlled by a timer operable on receiving a timing start signal to time out an OFF period during which the control valve is closed. A sensor device is responsive to completion of a cycle of operation to send a timing start signal to the timer. The supply of lubricant under pressure in the reservoir serves as both a power source for the operation of the valves and as a source of lubricant for delivery to the points of lubrication.
