A sleeve valve takes the form of one (or in the case of double sleeve valves, two) machined cylinders which fit concentrically between the piston and the cylinder block bore of an internal combustion engine having cross-flow induction/exhaust. These sleeves have inlet and exhaust ports machined in the periphery, analogous to a two-stroke motor ...

The sleeve-valve engine, which has been used on both automobiles and airplanes, powered speedy British fighters such as the Hawker Typhoon and Hawker Tempest. With their brute horsepower , they helped the Allies control the skies, provide air support for ground forces and eventually win the war.

A sleeve valve is a device typically used in a water supply or distribution system when there is a need to reduce high pressure or throttle flow. The sleeve valve consists of a cylindrical gate (tube) which slides over an inner sleeve.

What is a sleeve valve engine? A sleeve valve uses a sliding, sometimes rotating sleeve to control how much air and fuel get detonated with each compression stroke. The basic premise of igniting fuel and air to drive a set of pistons and turn a crankshaft is the same as it is with other internal-combustion engines.

The sleeve valve is a type of valve mechanism for piston engines, distinct from the usual poppet valve. Sleeve valve engines saw use in a number of pre–World War II luxury cars and in the United States in the Willys-Knight car and light truck. They subsequently fell from use due to advances in poppet-valve technology, including sodium cooling ...

At the heart of the Silent Knight engine lies the innovative double sliding sleeve design, a departure from the conventional poppet valve mechanism. Unlike traditional engines, which rely on valves that open and close to control the flow of air and exhaust gases, the sleeve-valve engine operates on a different principle.

2016年2月25日 · In their heyday of the early to mid 20th century, massive displacement sleeve valve engines powered the monstrous aircraft of the allied forces. Examples from the famed Bristol Engine Company powered aircraft such as the Hawker Sea Fury — famed for it’s post war racing tenure at Reno, and a variety of other multi-engine aircraft.

The sleeve valve is a type of valve mechanism for piston engines, distinct from the more common poppet valve. Sleeve-valve engines saw use in a number of pre-World War II luxury cars, sports cars, the Willys-Knight car and light truck, the British …

2012年2月27日 · A different method of controlling intake and expulsion of the air/fuel mixture, the sleeve valve system dispenses with conventional valvetrain, including poppet valves, spring, rocker arms and pushrods. Instead, a cylindrical sleeve nestles between the piston itself and the wall of the engine block.

As well as describing how Bristol incorporated the sleeve valve into their air-cooled radial engines, it covers the early experimental work, the development of the five engine types built (Perseus, Aquila, Taurus, Hercules and Centaurus) and some of their applications, and touches on the controversy over whether Fedden was right to pursue the sl...
