Abstract: A device for adjusting the displacement of a fluid pump includes a swashplate supported for pivotal movement about a first axis, and an engine having first and second cylinders. A first piston is located in the first cylinder and secured to the swashplate at a first side of the first axis. A second piston is located in the second cylinder and secured to the swashplate at a second side of the first axis opposite the first side. A plate is secured to the swashplate for pivotal movement about the first axis and is supported for rotary oscillation relative to the swashplate about a second axis. A pump includes a third cylinder and a first plunger located in the third cylinder, secured to the plate for pivotal movement about the first axis and rotary oscillation about the second axis. The plunger displaces fluid from the third cylinder as the plunger reciprocates.

Abstract: A pump-motor is used to move engine pistons to a position where the exhaust ports of a first cylinder are opened, and later to move the pistons to a position where the inlet ports and exhaust ports of the first cylinder are closed. Fuel is then injected into the first cylinder, and a starting motor is used to compress an air-fuel mixture in the first cylinder sufficiently to produce combustion of that mixture. A drive connection between a starting fluid-motor and the pistons is released. Fuel is injected into the second cylinder. The fuel-air mixture in the second cylinder is compressed sufficiently to produce combustion of that mixture.
