Abstract: A valve assembly includes an actuator adapted to drive movement of a valve member. The valve assembly also includes a bonnet coupled to the actuator, a valve body coupled to the bonnet, and a fluid end coupled to the valve body. The valve assembly further includes a quick connection system adapted to couple the fluid end to the valve body. The quick connection system includes a plurality of valve body lugs separated by a plurality of spaces, the plurality of valve body lugs extending radially outward from an axis. The quick connection system also includes a plurality of fluid end lugs configured to interact with the plurality of valve body lugs, the plurality of valve body lugs being arranged to axially align with the plurality of fluid end lugs to block axial movement of the fluid end with respect to the valve body.

Abstract: A reciprocating, multicylinder, 4-cycle internal combustion engine having a rotating power output crankshaft wherein the conventional connecting rod is replaced by a carrier member, attached to the piston and directed toward the open end of the cylinder and a guide member pivotally attached to the crankshaft throw, interconnecting with the carrier member in sliding relationship along a path lying in a plane normal to the axis of rotation of the crankshaft. It is preferred that two such cylinders are used in side-by-side, parallel arrangement with a power stroke in alternate cylinders so that each downward stroke of the pistons in unison involves a power stroke.
