    • ピストン機構は、クランクケース(4)と、3つのクランクピン(48,50,51)を備えたクランク軸(7)と、吸気開口部(14)および排気開口部(15)を有する作動チャンバ(10,11,12,13)を規定するダイバージングピストン(5,6)を有するシリンダ(1)と、2つの接続部材(27,28)を含み、接続部材のうち一方は中間のクランクピン(48)と協働し、他方は2つの外側クランクピン(50,51)と協働する。 シリンダ(1)の本体には、案内チャネル(16、17)が設けられ、その中に連接棒(19,20)が、交互の順序で配置され、その基部で、一方(27)または他方(28)の接続部材に装着され、2つの同期群の連接棒を構成する。 案内チャネル(16,17)は、シリンダのキャビティへの出口を備えたシリンダの作動表面の貫通切欠き(18)を備え、シリンダのキャビティに臨む同期群の連接棒の面(21)は、作動表面の可動部を形成する。 ピストン(5,6)は、ピストンの周縁部によって一方(19)または他方(20)の同期群の連接棒の側面(21)に順に装着され、相互に離間し、相互に挿入された2つの可動剛体、すなわち、反対方向へ移動する、接続部材−同期群の連接棒−ピストンを形成する。 この構成は、シリンダのキャビティにおいて、いくつかのダイバージングピストン(5,6)の配置を可能にし、ダイバージングピストン間に作動チャンバ(10,11,12,13)を形成し、作動チャンバ内で、異なる行程の独立した作動サイクルが同時に実施される。

    • PURPOSE:To reduce the bearing loss and fuel consumption by connecting an oscillating member having a freely movable supporting point to a piston through a joint at one end and to an output shaft at another end for its rotation. CONSTITUTION:Gas compressed by a piston 8 is ignited by an ignition plug 91 to burn, resulting in its expansion. The pressure of the burned gas pushes the piston 8 to move it toward an opposite combustion chamber 90 and moreover pushes a peripheral joining part 31 of an oscillating member 3 through a joint 7. In this case, since a pin part 32 of the member 3 supported by a spherical bearing 4 is restricted to be movable only in the rotating direction of an output shaft 1, the pushing force of the piston 8 acts as motion for rotating the output shaft 1 with a part where the member 3 fits into the spherical bearing 4 taken as a supporting point. Thus, the number of bearings can be reduced by applying the member 3 to an engine without using a crankshaft, and side pressure against the piston 8 can also be weakened for the reduction of bearing loss.

    • PROBLEM TO BE SOLVED: To operate a piston and rotate an output shaft by inserting a pin portion of a swing member, connecting an outer peripheral connecting portion thereof with the piston via a joint, into an oblique hole on a shaft end of the output shaft disposed on the same side as a cylinder head. SOLUTION: On a swing member 3 that is swingable in all directions via a spherical bearing 4, a protruded pin portion 32 is provided on an output shaft 1 side. The pin portion 32 is inserted into an oblique hole 113. In an engine, gas compressed by a piston 8 is combusted and expanded, of which the pressure in turn moves the piston 8 to an opposing combustion chamber 90. The pressing force of the piston 8 acts as the force to push an outer peripheral connecting portion 31 of the swing member 3 via a joint 7. On the other hand, the pin portion 32 with a spherical bearing 4 as the supporting point can move only in rotating direction of the output shaft 1. That is to say, the swing member 3 converts the pressing force of the piston 8 to the force to rotate the output shaft 1. Therefore, the piston 8 pushed by combusting pressure in one combustion chamber 90 conducts a compression stroke or exhaust stroke in the other combustion chamber 90.
