摘要： The disclosure provides rotary machines that include, in one embodiment, a shaft defining a central axis A, the shaft having a first end and a second end. The shaft can have a first gearbox disposed thereon defining one or more cavities therein. At least one contour is slidably received into an arcuate cavity in an exterior surface of the gearbox. The contour has a convex outer surface that cooperates with an inwardly facing curved surface of a housing to form a working volume. A gearbox mechanism consisting of gears, crankshafts, bearings and connecting rod creates an oscillatory motion 2 times per revolution such that the contour can navigate about the arcuate cavity without contacting the cavity at a high rate of rotating speed. Thus, said working volume can expand and compresses twice per rotatable shaft revolution.

The piston crown member consists essentially of forged steel. An integrated crosshead pin support and skirt member consists essentially of forged steel. The integrated pin support and skirt member is affixed to the piston crown member and is configured to support the crosshead piston pin. In a method of making a crosshead piston, a piston crown member is forged from steel. An integrated crosshead pin support and skirt member is forged from steel. The piston crown member is welded to the integrated crosshead pin support and skirt member.

摘要： An opposed-piston engine has a plurality of intake ports wrapped around the cylinder wall. It is desirable to obtain high swirl ratio flow with minimal pressure drop. A system have a generally-volute shaped plenum is disclosed. A centerline of the volute spirals inwardly. Furthermore, the cross-sectional area of the volute decreases in the direction of flow. The area is decreased as the flow from the plenum enters intake ports so that the velocity of flow in the plenum near the downstream end does not slow precipitously. The intake system may have multiple such volute-shaped plena coupled to mutually exclusive subsets of the intake ports. The volute shape leads to a high swirl ratio with limited drop in flow energy.
摘要翻译：相对活塞发动机具有围绕气缸壁缠绕的多个进气口。希望获得具有最小压降的高涡流比流。公开了一种具有大致蜗壳形的通风系统。蜗壳的中心线向内螺旋。此外，蜗壳的横截面积在流动方向上减小。随着来自气室的流量进入进气口，该区域减小，使得下游端附近的增压室中的流速不会急剧减慢。进气系统可以具有多个这样的蜗壳形凹槽，其耦合到进气口的互相排列的子集。涡流形状导致高涡旋比，流动能量有限下降。
