Automated manual transmissions can be semi-automatic or fully-automatic in operation. Several different systems to automate the clutch and/or shifting have been used over the years, but they will generally use one of the following methods of actuation for the clutch and/or shifting: hydraulic or electro-hydraulic actuation, [12] electro-mechanical, [13] pneumatic, [6] [14] [15] electromagnetic ...
There are many different types of hand pump available, mainly operating on a piston, diaphragm or rotary vane principle with a check valve on the entry and exit ports to the chamber operating in opposing directions. Most hand pumps are either piston pumps or plunger pumps, and are positive displacement. [1]

Push-button gear selector in a 2010–2014 Mitsubishi Fuso Aero Star bus. Many transmissions also include positions to restrict the gear selection to the lower gears and engages the engine brake. These positions are often labelled "L" (low gear), "S" (second gear) or the number of the highest gear used in that position (eg 3, 2 or 1).
A transmission (also called a gearbox) is a mechanical device which uses a gear set—two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine. [1] [2] Transmissions can have a single fixed-gear ratio, multiple distinct gear ratios, or continuously variable ratios. Variable ...

The top of the gear shift was designed to easily depress and activate an electric switch, i.e. when engaged by the driver's hand. When pressed, the switch operated a 12-volt solenoid , in turn, operating the vacuum clutch servo , thus disengaging the clutch and allowing shifting between gears.

A gear pump uses the meshing of gears to pump fluid by displacement. [1] They are one of the most common types of pumps for hydraulic fluid power applications. The gear pump was ...
