Abstract
A brake pressure limiting or reducing valve has its cut-off or operating pressure determined in accordance with vehicle loading through the agency of a simple tension spring connected directly between a movable member of the valve and a portion of the vehicle which is subject to vertical movement, relative to the valve, in response to changes in the loading of the vehicle.
