Abstract
An arrangement for a steam engine power plant with a steam generator, a steam buffer, and a timing valve for a steam engine of a displacement type with a range of cut-offs and motion in both driving and braking directions. Engine braking to the steam engine is provided when the timing valve opens the inlet to the cylinder to admit steam when the piston in the cylinder is moving toward top dead center while feed water is simultaneously being injected into the cylinder to collect the braking energy by being formed into steam. This steam and its energy can then be collected by the steam buffer for future use by the steam engine.
Claims19
A steam engine plant comprising a steam generator, a steam buffer, an adjustable timing valve with a range of cut-offs for both forward and reverse motion of a displacement type steam engine and supplying steam to the steam engine, and engine braking means controlled by said timing valve when positioned for braking of the engine in an opposite direction of rotation than a driving direction of rotation and opening a steam admission to a cylinder of the steam engine when a piston of the cylinder is moving up toward top dead center, and said engine braking means including means for simultaneously injecting water into the cylinder until the piston has reached top dead center.
A steam engine power plant, comprising a displacement type steam engine, a steam generator for supplying steam to said steam engine, a timing valve for regulating the supply of steam to said steam engine and synchronized with operation of said steam engine, and a steam buffer to store and release steam energy in said power plant and to receive braking energy from the steam engine.
A steam engine power plant, comprising a displacement type steam engine with at least one cylinder and cooperating piston, a valve for regulating entry of steam to said cylinder and synchronized with operation of said steam engine, a steam buffer for absorbing and storing steam energy and releasing steam for use by said engine, and a feed water supply to said engine to absorb braking energy of said engine and produce steam to be directed to said buffer.
