Abstract
A modular rotary discoid valve assembly includes a housing for positioning on an engine the piston and cylinder type. The housing includes an intake passage for conducting a working fluid to the cylinder and an exhaust passage for conducting the working fluid from the cylinder. The housing is formed with an internal cavity which intercepts the intake and exhaust passages, which cavity contains a rotary valve member having a window whose shape and/or angular positions on the disc varies with increasing distance from the disc axis. The window is so positioned that when the member is rotated to a first angular position, the window is located opposite the intake passage whereby the working fluid can flow along the intake passage through the window to the cylinder and when the member is rotated to a second angular position, the window is located opposite the exhaust passage so that the working fluid can flow from the cylinder through the window along the exhaust passage. Thus, the assembly alternately opens and closes the intake and exhaust passages in a periodic manner. Preferably also, the valve assembly includes a throttle bar slidably mounted in the housing parallel to the rotary valve member. The throttle bar has a hole which is positioned opposite the intake passage. The bar is movable toward and away from the axis of the rotary valve member between a first position which places the hole in the throttle bar opposite a radially inner portion of the valve member and a second position which places that hole opposite a radially outer portion of the valve member so that when the valve member is rotated, the open time of the intake passage can be controlled by the position of the throttle bar. A plurality of similar valve assemblies can be positioned adjacent to one another and concatenated so that they all operate in unison to control the working fluid flow to and from all the cylinders of a multi cylinder engine. The assembly is particularly suitable for converting an internal combustion engine so that it operates under steam power. Other applications for the assembly are also disclosed.
