A modular rotary discoid valve assembly includes a housing for positioning on an engine of 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 has an internal cavity which intercepts the intake and exhaust passages, which cavity contains a rotary valve member having a window whose size may vary with increasing distance from the disc axis and/or angular position on the member. The window is so positioned that when the member is rotated, it opens and closes the intake and exhaust passages in a periodic manner. The valve assembly also includes a throttle member mounted in the housing parallel to the rotary valve member. The throttle member has a hole which may be positioned opposite the intake passage. The throttle member is movable relative to the axis of the rotary valve member between a first position which places the hole in the shutter means opposite a first portion of the valve member and a second position which places that hole opposite a second 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 member. 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.

[ Having described our invention what is claimed as new and secured by Letters Patent is:] [1.] A rotary valve assembly comprisinga fluid conduit;a valve member having an open window;means for rotatably mounting the valve member on an axis with respect to the conduit so that when the valve member is rotated about said axis, the plate occludes the conduit except when the window is opposite the conduit;a control member having a through-hole therein;means for rotatably mounting the control member on said axis so that it is in face-to-face contact with the valve member and rotatable with the valve member through an angle greater than 360.degree., andmeans for adjusting the phase of the control member relative to the valve member while both members are rotating, between a first angular position wherein the control member may or may not occlude at least part of the window when the valve member is rotated to position the window opposite the conduit and a second angular position wherein the valve member occludes a different part of the window when the valve member is rotated to position the window opposite the conduit.
