The Pump Orifice acts as a flow restrictor, creating a pressure drop in the lubrication system. This restriction helps to control the flow rate of the lubricating oil, ensuring that it is delivered at the desired rate to the parts that require priority lubrication. It helps to allocate a predetermined portion of the pump output flow to the lube unit for the power train. Attributes:• Specific flow characteristics, laminar flow or turbulent flow, depending on the requirements of the lubrication unit• Durable materials to withstand the operating conditions and the flow of lubricating oilApplications: The Pump Orifice is used to control the flow of lubricating oil to engine parts such as bearings, camshafts, and crankshafts. It ensures that these parts receive a sufficient and controlled amount of lubrication for optimal performance and longevity of the power train.
