A jointed plunger assembly has a north end cap, a south end cap, and a body therebetween. The body includes at least one joint segment. In one embodiment, multiple joint segments are provided. Joints are formed throughout the body. In one embodiment, a flex rod is positioned in the north end cap, south end cap, and body. The flex rod is configured to flex and also seal fluid within the assembly, thereby preventing fluid leakage and helping to ensure that pumped fluid is moved upward and away from the pump. The assembly is configured to flex at each joint and is capable of flexing in various directions to follow the contours of the wellbore and the pump barrel. This configuration provides increased efficiency for deviated and horizontal pumping operations and helps the assembly components to wear more evenly, extending plunger life.

A compressor assembly for a compressed-air feed of a compressed-air supply system for operating a pneumatic system includes a compressor having a con-rod, a con-rod bearing, and a cylinder. The con-rod has a compressor piston. The compressor assembly further includes a drive having a drive shaft and a drive housing. The drive shaft is mounted in a drive bearing that is disposed within the drive housing. The drive bearing and the con-rod bearing partially or completely overlap one another in the axial direction, or the axial central plane of the drive bearing and the axial central plane of the con-rod bearing lie in one bearing plane. A crank disk is fixedly connected to an end portion of the drive shaft, the crank disk having a con-rod receptacle portion that is disposed so as to be eccentric to the drive shaft, the crank disk being rotatably connected to the con-rod.

An energy storage device is provided for a combustion chamber of an internal combustion engine. The energy storage device includes first and second end connectors connected to respective ones of a piston and crankshaft, and a flexible connection rod portion rotatably connected with the first and second end connectors. The flexible connection rod portion elastically buckles above a predetermined cylinder pressure threshold to store combustion energy and provide a more constant pressure combustion process.
