摘要： A compressor system, method and kit are provided for supplying pressurized air to a main storage reservoir of a locomotive. The compressor system includes a high-pressure cylinder having at least one outlet valve having a first set of sealing characteristics. The compressor system further includes a piping assembly connected to the outlet valve to selectively pass pressurized air to the reservoir. The piping assembly may comprise a T-fit coupler connected to first and second pipes for delivering the pressurized air to the reservoir. A check valve may be installed in a chamber defined in the T-fit coupler. The check valve has a second set of sealing characteristics different than the sealing characteristics of the outlet valve. The check valve is responsive to predefined operational conditions of the air compressor system so that when the compressor system is supplying pressurizing air to the reservoir the check valve is set to an open condition. When the compressor system stops supplying pressurizing air to the reservoir, the check valve is set to a closed condition. The combined sealing characteristics of the outlet valve and the check valve is chosen to limit backflow of pressurized air from the reservoir to the high pressure cylinder.

摘要： A fluid flow control valve having a cam disposed near an opening of a fuel passage. The cam is operable to be rotated about a shaft by the action of a float. As a fluid level in a tank changes, the cam rotates from an open position remote from the opening to a closed position (as illustrated) proximate the opening. A gap remains between the cam and the opening, thereby allowing the fluid level to be drawn down to the bottom of opening. Float has a generally wedge shaped cross-section to minimize the effect of wave action in the fluid.

摘要： An apparatus for removing and installing a rotor in an electric motor that is coupled to a shaft of a machine comprises a table having a support area for supporting and mounting the machine and motor. A tool is positioned on the table to move back and forth relative to the machine and motor, and engages the rotor to remove and install the rotor. A flange on the tool is secured to a temporary flange on a rotor sleeve. The tool also includes a piston concentrically aligned with the rotor and shaft to engage the shaft. A driving mechanism is linked to the piston to actuate the piston in a backward or forward direction relative to the machine and motor. The tool housing, responsive to movement of the piston, moves on the table in a direction opposite to the direction of movement of the piston to remove or install the rotor.

摘要： An actuator (16) for a rotor valve (10). The actuator includes a rack (86) for driving a pinion gear (87) of the valve. The rack is moved between first and second positions by the action of a first piston (88). Movement of the first piston and rack is selectively restricted in one direction by the movement of a moveable stop (104) from a withdrawn position to an extended position, thereby defining a third position of the rack. The moveable stop may be driven by a second piston (102). The first and second pistons may be powered by a common compressed air supply (122). The cross-sectional area of the first piston may be at least 1.4 times the cross-sectional area of the second piston to ensure that the force exerted by the first piston is not sufficient to displace the moveable stop from the extended position when the second piston is open to the compressed air supply.
摘要翻译：用于转子阀（10）的致动器（16）。致动器包括用于驱动阀的小齿轮（87）的齿条（86）。齿条通过第一活塞（88）的作用在第一和第二位置之间移动。通过可移动止动件（104）从撤回位置到延伸位置的移动，第一活塞和齿条的移动被选择性地限制在一个方向上，由此限定了齿条的第三位置。可移动止动件可以由第二活塞（102）驱动。第一和第二活塞可以由公共压缩空气供应源（122）供电。第一活塞的横截面积可以是第二活塞的横截面面积的至少1.4倍，以确保由第一活塞施加的力不足以在第二活塞对压缩空气供应是开放的。

摘要： A rotor valve (10) having a rotor seal (34) containing a centrally disposed opening (52) for directing an external pressure (Pe) to a rear surface (35) of the seal for applying a sealing force against a sealing surface (36). A projection (38) of the seal surrounding the opening is disposed within a bore (40) formed in a rotor (14) of the valve. An O-ring seal (44) defines the portion of the rear surface exposed to the external pressure. The rotor may be supported on one end by a bearing assembly (80) and may be open at the opposed end for receiving incoming water. Circumferentially distributed slip-surface plugs extend radially beyond the diameter of the rotor to support the rotor along an interior surface (39) of the valve body (12).
