Regulator/cs: Difference between revisions

Latest revision as of 01:03, 18 March 2025

Regulator is a control device found in steam engines . It serves a similar function to throttle in other powertrain types . Regulator sets the flow of steam from the boiler to the steam chest. Steam chest is an intermediary reservoir from where it can be admitted, using cutoff , to the vehicle's cylinders and propel the vehicle.

The regulator does not directly control a vehicle's acceleration. Rather, steam chest in combination with cutoff does, which is why it has a dedicated gauge to read pressure from. When the regulator is closed, steam stops flowing to the chest, but the vehicle stills accelerate until the chest runs out.

Delay in regulator operation doesn't need to exist only when closing it. If a vehicle uses an early version of superheaters, time it takes from opening the regulator until the steam chest start charging is delayed, too.

-Using the regulator control device (equivalent to throttle in other motorized vehicle types), the driver sets the amount of steam being admitted from the boiler to the steam chest. Steam chest is an intermediary reservoir from where the steam finally reaches the vehicle's cylinders.

-Based on the technology used, some vehicles may have early versions of superheaters that result in delay in response from the control device operation to the vehicle motion. Similarly, closing the regulator does not immediately stop admission of steam to the cylinders, but rather to the steam chest. Thus, the vehicle will not stop attempting to accelerate immediately, but only once the steam chest has depressurized.

-The steam in the chest is distributed alternately at both ends of the cylinders with every cycle. It pushes the pistons inside, which are mechanically connected to the driving wheels, thus propelling the vehicle. The used steam is then expelled through the blastpipe, where it mixes with smoke from the firebox in the smokebox, and together goes into the atmosphere through a chimney. The cycle repeats at every full rotation of the driving wheels.
