Orphan date February 2009 Image Axial piston engine example.jpg thumb The primary claimed benefit of the revolving cylinder , axial piston engine is that a four cycle, reciprocating piston engine can be achieved without the need for a complex and expensive valve train. The intake and exhaust flows are controlled by simple ports in the cylinder heads. Costs are further reduced because all cylinders at each end of the engine share a common fuel injector and or spark plug. Additionally, the designs are typically compact and lightweight. Most revolving cylinder, axial piston engine designs utilize a fixed, multi lobed barrel type cam and rollers on the pistons to control the reciprocating movement of the pistons. The benefit of this approach, versus a conventional crankshaft and connecting rod mechanism, is that the kinematics of the piston motion can be optimized with regards to combustion cycle efficiency. The primary drawback to the revolving cylinder, axial piston engine design is that rotating piston assemblies are subjected to centrifugal forces, which can result in significant friction losses. These centrifugal forces increase at the square of the angular velocity. So unless the engine is run at very low rotational speeds, the friction losses due to centrifugal forces acting on the piston ... engine which was developed in the early 1960s for torpedo propulsion.

The master cylinder is a control device that converts non hydraulic pressure commonly from a driver s foot into hydraulic pressure , in order to move other device s which are located at the other end of the hydraulic system, such as one or more slave cylinders . As piston s move along the bore of the master cylinder, this movement is transferred through the hydraulic fluid, to result in a movement of the slave cylinder s . The hydraulic pressure created by moving a piston inside the bore of the master cylinder toward the slave cylinder s compresses the fluid evenly, but by varying the comparative surface area of the master cylinder and or each slave cylinder, one will vary the amount of force and displacement applied to each slave cylinder relative to the amount of force and displacement that was applied to the master cylinder .

Orphan date December 2007 A wheel cylinder is a component in a drum brake system. It is located in each wheel and is usually at the top, above the shoes. Its responsibility is to exert force onto the shoes so they can contact the drum and stop the vehicle with friction . What connects these wheel cylinders to the shoes are usually small rods shaped like a birds beak. It is very similar to a master cylinder and functions in pretty much the same way, consisting of just a simple little plunger on the inside. On older vehicles these will begin to leak and hinder the performance of the brakes, but are normally inexpensive and easy to replace. The wheel cylinder consists of a cylinder that has two pistons, one on each side. Each piston has a rubber seal and a shaft that connects the piston with a brake shoe. When brake pressure is applied, the pistons are forced out pushing the shoes into contact with the drum. Wheel cylinders must be rebuilt or replaced if they show signs of leaking. automotive part stub Category Brakes ... more details
