An air motor assembly includes an exhaust block with an exhaust port that conveys exhaust air into an exhaust manifold. The exhaust port includes an expansion chamber that creates a pressure drop in the exhaust gas, thereby decreasing the temperature of the exhaust gas. The expansion chamber is defined between a first wall that is tangential to the air motor cylinder and a second wall that is transverse to an axis of the exhaust port. Poppet valves control actuation of a shuttle. The poppet valves are disposed on the exterior of the air motor assembly and are thermally insulated from the air motor assembly.

A drive assembly includes a drive motor at least in part contained in a housing and having a rotor rotating an output shaft. A selector mechanism, at least in part contained in the housing, is movable into one of a plurality of orientations corresponding to one of a plurality of drive motor settings. An actuator, at least in part contained in the housing, is arranged to move the selector mechanism into one of the plurality of orientations. The actuator has first and second pistons each disposed in a piston chamber of the housing for movement by hydraulic pressure. The second piston is arranged in contact with the first piston and configured to aggregate and transfer forces from hydraulic movement of the first piston and the second piston to move the selector mechanism.

A refrigeration device includes a compressor, a condenser, an expansion valve, an evaporator, intake electromagnetic valves and exhaust electromagnetic valves, two-position three-way electromagnetic valves or two-position five-way electromagnetic valves, a cylinder group, a volume-variable airproof container, two-position two-way electromagnetic valves and a generator. The cylinder group is composed of two or more cylinders, refrigerant flows successively through the compressor, the intake electromagnetic valves, the cylinder group, the exhaust electromagnetic valves, the condenser, the expansion valve and the evaporator and finally enters the compressor from the evaporator, the cylinder group can do work to generate electricity through atmospheric pressure in the volume-variable airproof container and compensates for electric energy consumed by the compressor, and therefore the electric energy can be saved.

A container storage facility has storage portions for storing containers, and supplies a purge gas to the interior of the containers. The container storage facility includes ejection portions that eject the purge gas, a gas supply device that controls the supply flow rate of the purge gas, a main pipe that conducts the purge gas output from the gas supply device, and branch pipes that are branched from the main pipe and are connected to the ejection portions. The ejection portions eject the purge gas regardless of whether or not containers are stored in the storage portions, and the gas supply device controls the supply flow rate of the purge gas so as to increase as the total number of containers stored in the storage portions decreases.

A cooling system that includes two or more fans that each have a chassis. The chassis includes a first face, a second face, and a sidewall. The fans then can be attached to each other by attaching a sidewall of a first fan chassis to a sidewall of a second fan chassis. An adjustable vane is attached perpendicularly and approximately equidistant between the fans, with an angular control element that is attached to the first fan chassis. The vane can be oriented such that the vane divides the airflow distributed to the fans. The vane then can be adjusted radially by the angular control element, which is attached to the fan chassis. If an impeller of a fan chassis fails the vane can be adjusted radially using an angular control element to distribute more airflow to the failed fan superimposing the non-failed fan chassis.

An agricultural machine or implement has a main frame section and at least one wing section, each having lift cylinders. A main shank frame may be pivotally attached to the main frame section and may have hydraulically adjustable gauge wheels. Wing shank frames may be pivotally attached to the wing sections and may also have hydraulically adjustable gauge wheels. Bypass circuits may be used to individually adjust the lift cylinders and gauge wheel cylinders. A controller or controllers is used to purge air from the lift cylinders, gauge wheel cylinders, cylinders used to raise the shank frames for transport, and from the bypass circuits. The purge routine may be selectable as individual steps, hydraulic subsystem purges, or as one automatic purge routine.
