  • Patent number: 5911564
    Abstract: The present disclosure is directed to a power plant, and especially two or more such power plants connected together. The power plant especially features a piston connected with a reciprocated but non-rotating piston rod which connects with a pump piston at the opposite end. Power is generated by the power piston and imparted through straight reciprocating motion to the pumped piston. Two or more of these power plants are operated together by connecting them together through a connective link so that operation of one times the operation of two or more units slaved to the first. Synchronized operation is obtained.
    Type: Grant

  • Patent number: 5464331
    Abstract: The present disclosure sets forth an improved engine and power output having an in-line powered end and pump end. The powered end incorporates a piston in a cylinder while the pump end also has a piston in a cylinder. A straight rod is connected between the powered end and the pump end so that axial reciprocating motion is created between the powered end and the pump end. The axial motion imparted to the straight rod by the powered end operates the pump end piston and creates axial reciprocating motion, thus eliminating intervening moving parts. A crankcase is included between the powered end and the pump end for enclosing and lubricating the moving components. The powered end preferably comprises a portion of an internal combustion engine.
