The Pump Actuator Orifice acts as a flow restrictor, creating a pressure drop in the fluid or airflow. This restriction helps control the flow rate and regulate the speed of the engine. By adjusting the size or shape of the orifice, the flow rate of fluid or air can be controlled, which in turn controls the speed of the engine. The orifice acts as a variable restriction, allowing for precise speed control based on the desired engine RPM.Attributes:• Specific flow characteristics, laminar flow or turbulent flow, depending on the requirements of the fluid• Durable materials to withstand the operating conditions and the flow of fluidsApplications: The Pump Actuator Orifice is used in the throttle body or carburetor to control the flow of air or fuel mixture, thereby regulating the engine speed. It helps maintain a desired RPM range for optimal performance, fuel efficiency, and emissions control.
