A lubrication system includes a lubricant supply reservoir, a supply line connecting the reservoir with one or more dispenser valves, a return valve and a pump. A control is operatively connected with a pump and with the return valve, the control being configured to operate the pump and the return valve such that a quantity of lubricant within the supply line flows out of the supply line and into the reservoir when a period of storage within the supply line of the quantity of lubricant exceeds an estimated period of effectiveness of the quantity of lubricant or a predetermined portion of the estimated lubricant effectiveness period.

An oil supply system of a vehicle includes: a first pump generating a first quantity of oil to cool a driving motor of a hybrid vehicle; a second pump generating a second quantity of oil to lubricate a friction lubrication element of the hybrid vehicle; a flow channel switching valve selectively switching a flow channel of the first quantity of oil and a flow channel of the second quantity of oil to connect the flow channel of the first quantity of oil to the friction lubrication element or connect the flow channel of the second quantity of oil to the driving motor; and a controller controlling an operation of the flow channel switching valve to supply a portion of the first quantity of oil to the friction lubrication element or a portion of the second quantity of oil to the driving motor.

A grease delivery with accumulated pressure system includes a grease accumulator comprising a first compartment containing a pressurized fluid and a second compartment containing a grease, a pressurized fluid source in communication with the first compartment, a grease reservoir connected to the second compartment through a supply conduit, and a discharge conduit extending from the second compartment to a receiving component.

A lubrication system for pneumatic machinery includes a lubricant vessel and a lubricant-control valve connected to a drop-dispensing body to discharge a demanded drop of lubricant inside a sealable drip chamber, which has a pressurized-gas inlet and a lubricated-gas outlet. A lubricator-pad assembly includes a lubricator-pad holder securing a lubricator pad to receive the drop of lubricant. Pressurized gas flows through the holder when exiting the drip chamber. A drop detector detects the demanded drop of lubricant. A controller connects to the drop detector and receives an indication that the demanded drop of lubricant has been detected. When a lubrication-demand tracker of the controller determines, based upon time or flow measurement or a combination thereof, that a lubrication threshold is reached, the controller initiates a drop cycle. If a maximum drop time passes before the demanded drop of lubricant is detected, the controller activates a missing-drop cycle.

A lubricating oil supply device includes: a supplier provided with a temporary storage for storing a lubricating oil temporarily, and configured to supply the lubricating oil stored in the temporary storage to a bearing together with compressed air; a lubricating oil supply path having one end portion connected to the temporary storage and the other end portion connected to a lubricating oil storage for storing the lubricating oil; a deliverer provided in the lubricating oil supply path, and configured to deliver the lubricating oil stored in the lubricating oil storage via the lubricating oil supply path to fill the temporary storage with the lubricating oil; an air supply path having one end portion connected to the supplier and the other end portion connected to a compressed air supplier for supplying the compressed air; and a pressure accumulator provided in the air supply path and configured to accumulate the compressed air.

A system for pumping lubricant in a gas transportation pipeline includes a pipeline robot and a control terminal system. The pipeline robot includes a lubricant position detection, module, a lubricant pumping module, an electro-hydraulic control system, a data acquisition and processing system, and a lubricant sucking port. The location at which the lubricant deposits can be detected online, and the lubricant staving in the gas transportation pipeline can be removed in real time. The system is highly automatic and efficient. Resistance against the natural as transportation is reduced effectively, the efficiency of transporting the natural gas is improved, and safety of transporting the natural gas is ensured.

A steam turbine valve drive apparatus in an embodiment includes a piston, a cylinder, a bidirectional pump, a servo motor, and a quick closing mechanism. The cylinder houses the piston in an inner space thereof, the inner space being partitioned by the piston into a first hydraulic chamber and a second hydraulic chamber. The quick closing mechanism executes a quick closing operation of closing the steam valve unit more quickly than the closing operation. Here, the quick closing mechanism executes the quick closing operation by feeding the working oil accumulated in an accumulator to the second hydraulic chamber and draining the working oil from the first hydraulic chamber.

A control block (1) for a lubrication system has a main body (2) with at least one inlet port (4) and at least one outlet port (6). A primary connecting line (8) fluidically connects the inlet port (4) to the outlet port (6). The main body (2) has at least one return port (10). A relief valve (12), in an open state, opens a connection between the primary connecting line (8) and the return port (10), and, in a closed state, builds up pressure in the primary connecting line (8), for lubricant to be conveyed to the at least one lubrication point via the outlet port (6). The relief valve (12) changes from a closed state to an open state when the pressure in the primary connecting line (8) exceeds a predefined pressure value.

A drive module for a vehicle including an electric machine, an inverter, a gearing assembly, and a cooling system. A first housing member thermally coupled with the inverter has a first set of heat exchange surfaces and a second housing member thermally coupled with the electric machine has a second set of heat exchange surfaces. The first and second sets of heat exchange surfaces each project into an interior volume cooled by an externally supplied liquid coolant which thereby defines a heat exchanger. A lower oil sump for collecting oil used to cool the electric machine may also include heat exchange surfaces projecting into the same heat exchanger. The gearbox may include an elevated oil sump which is supplied by the same oil pump circulating oil on the electric machine wherein the elevated oil sump gravity feeds oil onto selected surfaces within the gearbox.

A lubrication system (1) for lubricating lubrication points (2-1 to 2-8). The lubrication system includes a lubricant reservoir (4), lubricant injectors (6-1 to 6-8) for providing lubricant from the lubricant reservoir to the lubrication points, and a control unit (8) for controlling the flow of lubricant from the lubricant reservoir to the lubricant injectors. The control unit controls the lubricant injectors to simultaneously deliver lubricant to the lubrication points in predefined lubrication cycles (C.sub.L). The lubrication system also includes a condition monitoring unit (10) for monitoring the condition of the lubrication points. When the condition monitoring unit determines the condition of at least one of the lubrication points is abnormal, the control unit controls the lubricant injector being associated with the lubrication point having the abnormal condition to individually deliver an additional dose of lubricant to the associated lubrication point.
