  5. Hydraulic accumulator - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_accumulator

    One chamber contains the fluid and is connected to the hydraulic line. The other chamber contains an inert gas (typically nitrogen), usually under pressure, that provides the compressive force on the hydraulic fluid. Inert gas is used because oxygen and oil can form an explosive mixture when combined under high pressure. As the volume of the ...

  6. Free-piston linear generator - Wikipedia

    en.wikipedia.org/wiki/Free-piston_linear_generator

    The free-piston linear generator generally consists of three subsystems: combustion chamber, linear generator and return unit (normally a gas spring), which are coupled through a connecting rod. In the combustion chamber, a mixture of fuel and air is ignited, increasing the pressure and forcing the moving parts (connection rod, linear generator ...

  7. Auxiliary hydraulic system - Wikipedia

    en.wikipedia.org/wiki/Auxiliary_hydraulic_system

    An auxiliary hydraulic system delivers pressurized hydraulic fluid from a hydraulic pump to operate auxiliary equipment or attachments. The addition of an auxiliary hydraulic system to heavy construction equipment increases the versatility of the vehicle by allowing it to perform additional functions with different attachments.

  8. Engine–generator - Wikipedia

    en.wikipedia.org/wiki/Engine–generator

    An engine–generator is the combination of an electrical generator and an engine (prime mover) mounted together to form a single piece of equipment. This combination is also called an engine–generator set or a gen-set. In many contexts, the engine is taken for granted and the combined unit is simply called a generator. An engine–generator ...

    The second style of lubricator is a small one shot device that dispenses a measured amount of lubricant every time the starter is engaged. Installed directly onto the air inlet of the starter, the in-line lubricators are self priming pneumatic pumps that require a 1/4″ lubrication line piped from as far away as 4 feet.
