Abstract: A seal assembly includes first and second seal elements configured to lie adjacent to one another with a lower portion of each one disposed in a groove and an upper portion of each one projecting above the groove. The groove has a length disposed transverse to the direction of relative motion of a housing and a moving member and is located in the housing. The seal elements are further configured so that a contact surface of the upper portion of each seal element abuts the moving member and configured to allow independent movement of each seal element relative to each other in a direction transverse to the groove length. The seal elements are shaped to define a lubrication channel therebetween that is configured to allow the passage of a lubricant therein so as to lubricate motion of the seal elements relative to each other and relative to the moving member.

Abstract: An improved internal combustion engine of the four-stroke variable volume type operates by refraining from introducing substantial fuel into the working medium during the compression stroke until substantially maximum pressure of the working medium has been reached and utilizing at least one of the following processes: (a) causing combustion of fuel under substantially constant volume conditions; and (b) causing the power stroke to provide a larger volume to combustion products than the compression stroke provides to the working medium. Related methods are also provided.

Abstract: A method of operating an internal combustion engine having a housing, a piston mounted in the housing for complex motion about a plurality of axes and coupled to a shaft, and wherein occur phases of compression, combustion, and expansion in the housing, and wherein, in the compression phase, air introduced through an intake port into the housing is compressed by reducing volume of a compression chamber in the housing from an initial volume to a second volume that is less than the initial volume, and in the expansion phase, byproducts of combustion expand from the second volume to a third volume that is greater than the initial volume.
