A propeller like device with agitational or rotational movement located in a tank to prevent the content of the tank to build component segments.

An electric generator for the production of alternating current and voltage.

An electric motor driven by alternating electric current.

A dynamic compressor in which the gas is accelerated by the action of a bladed rotor and where the main flow is along the rotation axis of the rotor.

A physical object intended to compress and supply air or gas at medium pressure and medium volume flow.

A dynamic compressor in which one ore more impellers accelerate the gas and where the main flow through the impeller is radial.

A dynamic pump that contains impellers provided with vanes to generate centrifugal force to achieve the required pressure head.

A physical object that is driven by a prime mover by which energy is either constantly or periodically added to an amount of gas in order to increase its pressure.

An internal combustion engine in which ignition of the fuel injected into the cylinder is performed by the heat of compression of the air charge.

An electric generator for the production of direct current and voltage.

An electric motor for operation by direct current.

An energy transducer that transforms non-electric energy into electric energy.

An electric machine for transforming electric energy into mechanical energy.

An internal combustion engine that is an induction compression ignition exhaust engine which ignites a fuel air mixture.

A physical object that is intended to deliver or exhaust volumes of vapour or gas at low differential pressure.

An internal combustion engine that is a reciprocating engine in which gaseous fuel is mixed with air to form a combustible mixture in a cylinder which is fired by spark ignition.

A turbine that compresses air which is then mixed with fuel for combustion and expansion through a turbine section to generate relatively high power output for either mechanical drive or power generation.

A turbine in which liquid forces are driving the rotor by the reaction of acceleration of subject liquid flow in the runner while the pressure drops.

An internal combustion engine that is an induction compression ignition exhaust engine which ignites a petrol air mixture with an electric spark.

A physical object that adds or removes mechanical energy to a fluid, either constantly or periodically.

A positive displacement compressor in which forced reduction of gas volume takes place by the movement of a displacing element in a cylinder or enclosure.

A positive displacement pump which contains a displacing element intended to be moved in a reciprocating movement to exert pressure on a fluid, typically moving within a cylindrical space.

A positive displacement compressor in which compression displacement is effected by the positive action of rotating elements.

A positive displacement pump that consists of a chamber containing gears, cams, screws, vanes, plungers or similar elements actuated by relative rotation of the drive shaft or casing and which has no separate inlet and outlet valves.

A thermodynamic turbine in which steam is made to do work by expanding so as to create kinetic energy by acting on moving blades attached to a disc or drum.
