    摘要： A protection mechanism for a lubricant reservoir is mounted within a valve protection chamber disposed on an actuator. The protection mechanism includes a valve actuating plate and an elastic member biasing the valve actuating plate upwards. The actuator is pushed upwards by a rising level of lubricant as the lubricant reservoir is filled. When the reservoir is full, the actuator causes the valve actuating plate to contact a valve stem. The valve actuating plate pushes the valve stem up to shut off a flow of lubricant to the reservoir through the shut off valve. During an overfill event the actuator shifts upward due to the rising level of the lubricant in the reservoir. As the actuator shifts upward, the elastic member compresses such that valve actuating plate remains static relative to the lubricant reservoir as actuator rises.

    摘要： A piston for a single-stroke pump includes a pump rod, a seal ring extending about the pump rod and having a central bore, and a retaining device disposed on the pump rod and retaining the seal ring on the pump rod. In a forward stroke, the seal ring is in a first position whereby the seal ring sealingly engages the pump rod such that the seal ring and pump rod drive a fluid out of the pump chamber. When transitioning to a return stroke, the seal ring is maintained stationary relative to the pump cylinder until retaining device engages seal ring, such that seal ring is in a second position. With the seal ring in the second position, a flow path is opened between the seal ring and the pump rod, allowing fluid to flow into the pump chamber to prime the pump the next pump cycle.

    摘要： A lubrication system for a hydraulic hammer is disclosed. The lubrication system includes a housing having a first chamber, and a control valve, disposed proximal to a first end of the first chamber, moveable from a closed position to an open position. A piston is received within the first chamber and moveable between a first position and a second position. The piston includes a first end having a cavity, and a second end facing towards a second chamber, which receives hydraulic fluid therein. In the second position, when the first chamber is filled with air in the first position of the piston, the cavity defined at the first end of the piston maintains pressure of the air less than a biasing force of a resilient member that keeps the control valve in the closed position.

    摘要： A system for emergency lubrication, with a lubricant pump (113) and with at least one outlet opening (125) for delivering lubricant to at least a first lubrication point (107) of a transmission (101), in particular a transmission of a wind turbine. The system includes a first cavity (203), and the lubricant pump (113) is designed to convey at least some of the lubricant into the first cavity (203). The first cavity (203) is designed to store the lubricant intermediately and to act upon the intermediately stored lubricant with positional energy. In addition, there is a lubricant-conveying connection between the first cavity (203) and the outlet opening (125).

    摘要： A rotating control device (RCD) can include an automatic RCD oiling system for providing lubricating oil to the RCD and preventing wellbore fluid under wellbore pressure from entering the RCD. The automatic RCD oiling system can include an oil pressure intensifier, a pump, and a pump flow controller. The oil pressure intensifier can include a piston assembly for maintaining a pressure differential between pressure from the lubricating oil on a rod side of the piston assembly and an annulus pressure corresponding to a wellbore pressure on the piston side of the piston assembly. The pump can pump lubricating oil from tank into passages to a bearing assembly of the RCD and a pump flow controller that controllably directs lubricating oil to the piston assembly and a return passage to the tank or the pump.
