Valve cam mechanism

Flexible Wedge The flexible wedge gate valve illustrated in Figure 6 is a one-piece disk with a cut around the perimeter to improve the ability to match error or change in the angle between the seats. The cut varies in size, shape, and depth. A shallow, narrow cut gives little flexibility but retains strength. A deeper and wider cut, or cast-in recess, leaves little material at the center, which allows more flexibility but compromises strength.

This is the smallest unit of the machine and complete, its characteristics can not be separated out and meet all technical requirements. (For example, gears, shafts bike). Can put all the machine parts into two groups: - Detailed machine for general use (for example, bolts, gears; axis) is the machine parts used in many different machines. Details specific use machines have been used only in a certain number. (eg, crankshaft, valves, cam ...)

DIESEL ENGINES pushrods and rocker arms transfer the reciprocating motion generated by the camshaft lobes to the valves and injectors, opening and closing them as needed. The valves are maintained closed by springs. As the valve is opened by the camshaft, it compresses the valve spring. The energy stored in the valve spring is then used to close the valve as the camshaft lobe rotates out from under the follower. Because an engine experiences fairly large changes in temperature (e.g.

Pro Engineer is a 3D-CAD software for designing graphics for the motion simulation in mechanical design, mechatronics, mechanical power, automation ...Create a new assembly called valve_cam. Uncheck Use default template. The New File Options dialog box appears. Create a new datum plane through the axis of top hole of the shaft_mount. This datum plane should be parallel with ASM_TOP. Create a pin connection between rocker arm and shaft mount.
