Filed:

Jan 26, 1999

Appl. No.:

9/236774

Inventors:

Steven Lambert - Burbank CA
Michael Lambert - Los Angeles CA

International Classification:

F01L 706

US Classification:

123 80D

Abstract:

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.

In some applications, the rotary valve member itself can function as the throttle member.

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.
