A pump is a device that moves fluids, or sometimes slurries, by mechanical action, typically converted from electrical energy into hydraulic energy.
A continuously variable transmission (CVT) is an automated transmission that can change through a continuous range of gear ratios. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant angular velocity while the vehicle moves at varying speeds.
The Jaguar Mark X, later renamed the Jaguar 420G, was British manufacturer Jaguar's top-of-the-range saloon car for a decade, from 1961 to 1970. The large, luxurious Mark X not only succeeded the Mark IX as the company's top saloon model, but radically broke with both its predecessor's styling and technology.
Hydraulic machines use liquid fluid power to perform work. Heavy construction vehicles are a common example. In this type of machine, hydraulic fluid is pumped to various hydraulic motors and hydraulic cylinders throughout the machine and becomes pressurized according to the resistance present. The fluid is controlled directly or automatically by control valves and distributed through hoses, tubes, or pipes.
Power steering is a system for reducing a driver's effort to turn a steering wheel of a motor vehicle, by using a power source to assist steering.
A linear actuator is an actuator that creates linear motion, in contrast to the circular motion of a conventional electric motor. Linear actuators are used in machine tools and industrial machinery, in computer peripherals such as disk drives and printers, in valves and dampers, and in many other places where linear motion is required. Hydraulic or pneumatic cylinders inherently produce linear motion. Many other mechanisms are used to generate linear motion from a rotating motor.
The Jaguar S-Type is a saloon car produced by Jaguar Cars in the United Kingdom from 1963 to 1968. Announced 30 September 1963 it was a technically more sophisticated development of the Mark 2, offering buyers a more luxurious alternative without the size and expense of the Mark X. The S-Type sold alongside the Mark 2, as well as the Jaguar 420 following its release in 1966. A retro-styled vehicle with the same name was also produced, based on the design of the original S-Type vehicles.
Motor drive means a system that includes a motor. An adjustable speed motor drive means a system that includes a motor that has multiple operating speeds. A variable speed motor drive is a system that includes a motor and is continuously variable in speed. If the motor is generating electrical energy rather than using it – this could be called a generator drive but is often still referred to as a motor drive.
A hydraulic brake is an arrangement of braking mechanism which uses brake fluid, typically containing glycol ethers or diethylene glycol, to transfer pressure from the controlling mechanism to the braking mechanism.
The Maserati Khamsin is a grand tourer produced by Italian automobile manufacturer Maserati between 1974 and 1982. The Khamsin was sold alongside the DeTomaso-based Maserati Kyalami - also a V8 GT car - between 1976 and 1982.
An axial piston pump is a positive displacement pump that has a number of pistons in a circular array within a cylinder block.
DIRAVI is the name given by Citroën to its proprietary power steering system, first seen in 1970.
A hydraulic motor is a mechanical actuator that converts hydraulic pressure and flow into torque and angular displacement (rotation). The hydraulic motor is the rotary counterpart of the hydraulic cylinder as a linear actuator. Most broadly, the category of devices called hydraulic motors has sometimes included those that run on hydropower but in today's terminology the name usually refers more specifically to motors that use hydraulic fluid as part of closed hydraulic circuits in modern hydraulic machinery.
The following outline is provided as an overview of and topical guide to automobiles:
A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy. Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic. They generate flow with enough power to overcome pressure induced by a load at the pump outlet. When a hydraulic pump operates, it creates a vacuum at the pump inlet, which forces liquid from the reservoir into the inlet line to the pump and by mechanical action delivers this liquid to the pump outlet and forces it into the hydraulic system. Hydrostatic pumps are positive displacement pumps while hydrodynamic pumps can be fixed displacement pumps, in which the displacement cannot be adjusted, or variable displacement pumps, which have a more complicated construction that allows the displacement to be adjusted. Hydrodynamic pumps are more frequent in day-to-day life. Hydrostatic pumps of various types all work on the principle of Pascal's law.
The Jaguar 420 and its Daimler Sovereign equivalent were introduced at the October 1966 London Motor Show and produced for two years as the ultimate expression of a series of "compact sporting saloons" offered by Jaguar throughout that decade, all of which shared the same wheelbase. Developed from the Jaguar S-Type, the 420 cost around £200 more than that model and effectively ended buyer interest in it, although the S-Type continued to be sold alongside the 420/Sovereign until both were supplanted by the Jaguar XJ6 late in 1968.
Hydrosteer was the name given by George Kent Ltd and Cam Gears Limited through Hydrosteer Limited of Luton, England, to its automotive power steering system. Initially Hydrosteer manufactured the Ross-Link system for commercial vehicles from 1953 under licence from Ross Gear and Tool of U.S.A. Their own product available from 1961 was based on a cam and peg system and was characterised by its fully integrated design and variable steering ratio. This configuration provided automotive manufacturers with a fairly simple design modification to provide a power steering option for cars fitted with a conventional cam and peg steering box. It was fitted to several, mainly British, luxury automobiles of the era. Production continued up to 1973, with just over 105,000 units being produced. As a "first generation" assistance system, applications were somewhat varied in their tuning of the many system dynamics to the specific vehicle. The system fell out of use as powered rack and pinion steering systems gained in popularity.
The second generation of the Subaru Impreza compact car was introduced in 2000 and manufactured up to 2007 by Subaru in Ota, Gunma, Japan, in both sedan and five-door wagon bodystyles, as well as two intermediate facelifts throughout its lifespan.
Variable valve lift (VVL) is an automotive piston engine technology which varies the height a valve opens in order to improve performance, fuel economy or emissions. There are two main types of VVL: discrete, which employs fixed valve lift amounts, and continuous, which is able to vary the amount of lift. Continuous valve lift systems typically allow for the elimination of the throttle valve.
