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 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 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 lubricant recovery system for a heat exchange system, and a heat exchange system. The heat exchange system includes a compressor, a condenser, an expansion device and an evaporator connected in sequence to form a loop, and further includes a reservoir for storing lubricant and in communication with the compressor, and the lubricant recovery system includes: a first flow path disposed between a suction chamber of the compressor and the reservoir, and having a first pump and a first filter, wherein the first pump is configured to pump a part of the lubricant in the suction chamber to the reservoir, and the first filter is disposed upstream of the first pump for filtering the lubricant; and/or a second flow path disposed between the evaporator and the suction chamber, and having a second pump and a second filter.

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 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 device and method for dispensing a friction-coefficient-optimizing mixture of at least one lubricant and at least one grit into the gap between a rail wheel of a rail vehicle and a rail. The device includes a reservoir for the lubricant, a reservoir for the grit, a metering unit for metering the lubricant, a metering unit for metering the grit, a delivery apparatus for delivering the lubricant, a delivery apparatus for delivering the grit, and a common dispensing nozzle. The apparatus for delivering the lubricant and the apparatus for delivering the grit are separate from each other and end in the common dispensing nozzle, the friction-coefficient-optimizing mixture therefore not being formed until the dispensing, and an additional compressed air line is provided, which ends in the common dispensing nozzle.

Embodiments of the present disclosure include a remote well servicing system including a control unit and a remote servicing manifold. The control unit further includes a service fluid source and a control system. The remote servicing manifold further includes a fluid input line coupled to the service fluid source, a fluid output line couplable to a well component, and a valve coupled to the fluid input line and the fluid output line, wherein the valve, when actuated, places the fluid input line in fluid communication with the fluid output line and permits delivery of a service fluid from the service fluid source to the well component. The remote servicing manifold also includes a control line coupling the valve and the control system wherein the control system controls actuation of the valve via the control line.
