摘要： A fluid pump has an integral filament-wound housing bonded to internal parts of the pump. The pump housing is made of composite material (such as fiberglass strands coated with epoxy resin) wound about an adapter, pumping members and an output flange. Once hardened, the housing, adapter, pumping members and output flange are permanently bonded together to form a unitary structure. Pump efficiency is greatly enhanced because the pump housing forms a fluid-tight seal between (a) pumping members and (b) between pumping members and the housing and further prevents rotation of the pumping members in response to torque forces during pump operation.

摘要： The invention is an improvement in a centrifugal pump of the type having two or more pumping stages. Each stage includes a stationary diffuser and a companion rotatable impeller with a wear ring set arranged between the diffuser and impeller of each stage. The improvement includes a bearing ring formed of a hard material, preferably harder than sand. A second bearing ring is formed of a resilient material in thrust-absorbing, sealing contact with the first ring whereby grit or sand may be lodged between the rings without substantially impairing such contact of the rings with one another. In the first embodiment, the bearing rings perform a sealing function as well as absorb axial thrust. In the second embodiment, a primary sealing function is provided by a separate annular disc with which the impeller is in contact.
摘要翻译：本发明是具有两个或多个泵送级的类型的离心泵的改进。每个阶段包括固定的扩散器和伴随的可旋转的叶轮，其具有设置在每个阶段的扩散器和叶轮之间的耐磨环。改进包括由硬质材料形成的轴承环，优选比沙子更硬。第二轴承环由弹性材料形成，以与第一环进行推力吸收，密封接触，由此砂粒或砂可以被放置在环之间，而基本上不会损坏环彼此的这种接触。在第一实施例中，轴承环执行密封功能以及吸收轴向推力。在第二实施例中，主密封功能由与叶轮接触的单独的环形盘提供。

摘要： A brake assembly includes a rotatable disc which is movable along its axis of rotation. Brake pads on caliper arms are engageable with opposite sides of the disc. An actuator assembly is operable to move the caliper arms to press the brake pads against opposite sides of the disc. To accommodate movement of the disc along its axis of rotation, the actuator assembly is movable along the axis of rotation of the disc under the influence of force transmitted through the caliper arms to the actuator assembly. The caliper arms have arcuate end surfaces which engage arcuate surfaces on the brake pads.
