Abstract
A lubrication system comprises a reservoir for lubricant, lubricant delivery means to deliver lubricant to at least one component to be lubricated, an injector associated with each component, a control system to control the opening and closing of each injector and scavenge means to remove surplus lubricant from around each component and return it to the reservoir. Each injector comprises a pulsative injector, controlled by the control system to deliver lubricant to its associated component in a series of discrete pulses. In a preferred embodiment both the delivery of oil to each component and the scavenging of oil from each component are controlled in response to sensed conditions of that component.
