ABSTRACT:
The system comprises a plurality of engine subassemblies having double-acting pistons, for generating power and pressuring fluid for work. Each piston undergoes a power stroke, under the influence of energized fluid addressed thereto and, during the power stroke, the piston(s) pressurizes fluid for powering ancillary fluid-powered machines. The latter fluid is admitted through channels formed in the pistons to lubricate the pistons in their reciprocation in cylinders. Each of the cylinders is enclosed in a surrounding coolant chamber. A carrier element is employed for effecting a common translation of all pistons, and the carrier element supports extending actuators which, through a "lost motion" arrangement, actuate a valve-operating system coupled to the heads of the cylinders. Limit-stop springs, interposed between the carrier element and housings (which confine the cylinders) delimit the travel of the pistons. Also, the carrier element has a ferrous-metal rod projecting therefrom for close-coupled engagement with an electro-magnetic coil for, at least, effecting a start-up of the system.
