11. When the trigger is squeezed, the throttle valve opens, allowing the pressurized air to flow into the piston. 12. Typically used on small engines, notably motorcycles, enrichments work by opening a secondary fuel circuit below the throttle valves . 13. Regulated air entering passes through the throttle valve which is typically controlled by a trigger in the hand grip. 14. The year 2000 again saw a total redesign of the engine, now with dual throttle valve electronic fuel injection. 15. There is a Throttle Valve in the control valve body that is connected to the throttle linkage via a cable. 16. When the throttle is opened, it releases i . e . lessens the pressure which lets the throttle valve fall. 17. The steam dome with throttle valve was on the first boiler ring and was cowled together with pneumatically operated sandbox. 18. As air density decreases with increased altitude, the throttle valves were progressively opened in response to the reducing atmospheric pressure. 19. It is normally installed between the astern throttle valve and the astern elements of the low pressure ( LP ) turbine. 20. The orifice or throttle valve creates a pressure drop between the high pressure condenser section and the low pressure evaporator section.
