摘要： A fluid pressure responsive member is shifted in accordance with the pressure differential between two lines either one of which can be a suction line with the other line being a discharge line of a reversible compressor. The fluid pressure responsive member has an arcuate recess formed therein which serves as a secondary suction port which provides fluid communication to the offset cylindrical chamber from the suction line in accordance with the position of the fluid pressure responsive member. Because the porting is responsive to the pressure differential between the two lines, the changeover of the porting is automatic upon the reversal of the operation of the compressor.
摘要翻译：流体压力响应构件根据两条管线之间的压力差而移动，两条管线之间的压力差可以是吸入管线，另一条管线是可逆压缩机的排放管线。流体压力响应构件具有形成在其中的弧形凹部，其用作次级吸入口，其根据流体压力响应构件的位置提供与吸入管线的偏移圆柱形腔室的流体连通。由于端口响应于两条线之间的压力差，因此在压缩机的操作反转时，端口的切换是自动的。

摘要： A spool valve is located within the shell of a hermetic compressor unit and shifted by a solenoid valve to direct the discharge of the compressor through either of two lines through the shell. Depending upon the line used as the discharge line, the compressor is suitable for either heating or cooling and is the equivalent of a reversible compressor. Alternatively, a spool valve can connect the suction line of a compressor to either of two lines extending through the compressor shell.
摘要翻译：滑阀位于封闭式压缩机单元的外壳内，并通过电磁阀移动，以将压缩机的排放通过两条线穿过外壳。根据用作排放管线的管线，压缩机适用于加热或冷却，相当于可逆式压缩机。或者，滑阀可以将压缩机的吸入管路连接到延伸穿过压缩机壳体的两条管线中的任一条。

摘要： A fluid pressure responsive member is shifted in accordance with the pressure differential between two lines either one of which can be a suction line with the other line being a discharge line of a reversible compressor. The fluid pressure responsive member has a pair of arcuate recesses formed therein which serve as secondary suction ports which provide fluid communication to the elliptical chamber from suction lines in accordance with the position of the fluid pressure responsive member. Because the porting is responsive to the pressure differential between the two lines, the changeover of the porting is automatic upon the reversal of the operation of the compressor.

摘要： Apparatus and method for dissipating heat in a generator. A rotor having support wedges between each of its poles is mounted on a bored shaft in which a bored spindle having helical grooves along its outer diameter is fixed. A cooling medium is circulated through the bored shaft upon rotation of the shaft. The shaft has at least one outlet and one inlet through which the cooling medium can radially exit and return, respectively. Each of the support wedges has an inlet and an outlet between which a bore extends. In a preferred embodiment, a manifold is disposed about the bored shaft and mated to each of the support wedges so as to circulate the cooling medium from the bored shaft to the support wedges and back to the bored shaft, thereby dissipating heat from the generator rotor. In alternate embodiments more than one manifold is used to circulate the cooling medium through the support wedges.
