trip gear वाक्य

Smaller stationary steam engines generally have a fixed cutoff point while, in large ones, the speed and power output is generally governed by altering the cutoff, frequently under trip gear.
The valve is opened by the mechanical valve gear mechanism, and when the trip gear trigger releases the mechanism the valve is snapped closed, usually by a spring acting against a dashpot.
This engine uses separate valves for the steam and the exhaust to allow natural drainage . It also has a Reynolds trip gear, which uses a spring to cause the engagement of the hook with the catch plate.
