A rotary 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. 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 ass...
[ What is claimed is:] [1.] A rotary valve assembly comprisinga block defining a concave valve seat having cylindrical curvature about an axis, said valve seat defining a sector of 180.degree. or less;means defining a passage extending through said block to said valve seat;a cylindrical valve member having a wall with an open window, the diameters of the valve seat and valve member being substantially the same;means for rotatably mounting the valve member on said axis so that when the valve member is rotated about said axis, the valve member occludes sai...
