Abstract
In an engine pressurized prelubricator assembly or an assembly for providing pressurized lubricant to the center bearing of an exhaust-driven turbocharger, flow restrictor means are disposed in the conduit connecting the engine lubricant system to the reservoir means for storing pressurized lubricant. The flow restrictor means restricts flow of lubricant into the reservoir means thereby preventing starving of the engine lubricant system for lubricant during charging of the reservoir means with lubricant. The flow restrictor means permits substantially unrestricted flow of lubricant from the reservoir means to the engine or center bearing when lubrication is required. A manually operated valve means is provided for use in the conduit connecting the engine lubricant system to the reservoir means. The rate of flow of lubricant through the valve and hence to and from the reservoir means is selectable by manually operating the valve. The rate of lubricant flow is manually selected responsive to the operating condition of the engine.
