摘要: An improved self-injection reciprocating diesel or stratified charge type engine which utilizes pressure in the cylinder to air inject fuel into an adjacent combustion chamber. The combustion chamber and the cylinder space are connected by three separate passages, a small fuel passage, a primary air passage, and a secondary air passage, the secondary air passage being smaller than the primary but considerably larger than the fuel passage. Fuel is delivered by pump pressure to the fuel passage well before top dead center of the piston. As the piston approaches top dead center, it blocks the primary air passage; the resulting rapid pressure increase in the cylinder over that in the combustion chamber causes air from the cylinder to flow through the secondary air passage and create a swirl in the combustion chamber, and air to flow through the fuel passage which atomizes part and ejects the remainder of the fuel onto the wall of the combustion chamber from where it evaporates and burns. The secondary air passage, subsequent to the blocking of the primary air passage, provides the flow path for most of the air flowing from the cylinder to the combustion chamber and hence, controls the pressure differential between the cylinder and combustion chamber. Because the fuel passage is substantially smaller than the secondary air passage, it may be cooled without excessive heat losses and at the same time prevent premature evaporation and decomposition of the fuel. This separation and function of the secondary air and fuel passages in combination with selfinjection, swirl creation in the combustion chamber, initial atomization of a small fraction of the fuel, and surface deposition of most of the fuel followed by evaporation are the distinguishing features of this invention.

摘要: A low inertia, rapid response, low volume check valve utilizes two body members positioned in end-to-end alignment. The valve bodies have end faces which are clamped into sealing engagement with each other. A shallow cylindrical chamber is formed in one of the end faces and carries a very thin, disc like valve closure member which floats between a closed position against the face of the inlet body and an open position against the face of the outlet body. The closure member is relieved to permit fluid flow therearound and into depressions in the face of the outlet body. Preferably the outlet passage is formed by stainless steel tubing such as hypodermic tubing carried in the outlet body to provide an inexpensive outlet passage with a minimum of contained volume.
