WITH SEPARATING MEANS OR GUARD FOR SOLID MATTER IN WORKINGFLUID (E.G., DEBRIS, ETC.):
(under the class definition) Device comprising (a) means to divide out solid elements carried along by the working fluid* from the working fluid or (b) means to shield or protect part of the device from solid elements in or carried along by the working fluid.
(1) Note. Elements carried along by the working fluid which are separated from the working fluid may include dust, sand,
pieces of the device which have entered the working fluid as a result of structural failure, etc.
(2) Note. A means which shields a part of the device from human hands is included in this subclass.
(3) Note. A means which merely separates moisture or condensate from working fluid in the device is not included in this subclass.
