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.

A powered pump system comprising: a) a power end having 1) a fluid-isolated cylinder with, 2) a cylinder head, 3) an axially directed power piston in said cylinder defining a combustion chamber in said cylinder between said cylinder head and said power piston, and 4) air/fuel mixing means connected

A powered pump system comprising: a) a power end having 1) a fluid-isolated cylinder with, 2) a cylinder head, 3) an axially directed power piston in said cylinder defining a combustion chamber in said cylinder between said cylinder head and said power piston, and 4) air/fuel mixing means connected to deliver a mixture of air/fuel into said combustion chamber for timed ignition to provide power to said power piston moving said power piston with a power stroke; b) a pump end having 1) a fluid isolated pump cylinder with 2) a pump cylinder head, 3) an axially directed pump piston in said pump cylinder defining a pumped chamber between said pump cylinder head and said pump piston, and 4) inlet and outlet passage means connected to said pumped chamber to enable pumped fluid to flow there through; c) an elongate straight rod having two spaced ends wherein said rod at one end is connected to said power piston and the second end is connected to said pump piston wherein said rod delivers an axial power stroke to said pump piston, and wherein said rod is connected to said pump piston and said power piston to preclude rod movement other than axial sliding movement so that said pump piston and rod piston are jointly axially aligned with said rod and said rod is connected to said pistons without rod flexure or deflection; and d) a closed shell interposed between said power end and said pump end wherein said closed shell encloses said straight rod and a lubrication system for said rod, and said closed shell is constructed and arranged to isolate said power end from said pump end.
