   Fixed displacement vane pump. A rotary vane pump is a positive-displacement pump that consists of vanes mounted to a rotor that rotates inside a cavity. In some cases these vanes can have variable length and/or be tensioned to maintain contact with the walls as the pump rotates.

4. Pump - Wikipedia

   en.wikipedia.org/wiki/Pump

   Screw pumps – the shape of the internals of this pump is usually two screws turning against each other to pump the liquid; Rotary vane pumps; Hollow disc pumps (also known as eccentric disc pumps or hollow rotary disc pumps), similar to scroll compressors, these have an eccentric cylindrical rotor encased in a circular housing. As the rotor ...

5. Hydraulic motor - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_motor

   A critical element in vane motor design is how the vane tips are machined at the contact point between vane tip and motor housing. Several types of "lip" designs are used, and the main objective is to provide a tight seal between the inside of the motor housing and the vane, and at the same time to minimize wear and metal-to-metal contact.

6. Variable displacement pump - Wikipedia

   en.wikipedia.org/wiki/Variable_displacement_pump

   Piston pumps can be made variable-displacement by inserting springs inline with the pistons. The displacement is not positively controlled, but decreases as back-pressure increases. Another variation is the variable-displacement vane pump, a type that has found usage in motor vehicle automatic transmissions, such as the General Motors Hydra-Matic.

7. Oil pump (internal combustion engine) - Wikipedia

   en.wikipedia.org/wiki/Oil_pump_(internal...

   Gear pumps [1] [2] trochoid pumps [3] and vane pumps [a] are all commonly used. Plunger pumps have been used in the past, but these are now only used rarely, for small engines. To avoid the need for priming, the pump is always mounted low-down, either submerged or around the level of the oil in the sump. A short pick-up pipe with a simple wire ...

   The last image we have of Patrick Cagey is of his first moments as a free man. He has just walked out of a 30-day drug treatment center in Georgetown, Kentucky, dressed in gym clothes and carrying a Nike duffel bag.

9. Comparison of pumps - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_pumps

   Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface water (e.g., irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (e.g., potable water pumping ...
