- Pneumatic quick couplers (also referred to as air couplers, or pneumatic quick disconnects), are primarily used for pneumatic applications, connecting air tools, hoses, or other implements to compressed air supplies.
- The coupler half contains a shut-off valve that is automatically opened when a mating nipple is inserted and automatically closes when the nipple is removed.
- Parker pneumatic couplings come in three basic designs: general purpose/manual connect, general purpose/push-to-connect, and special purpose.
- The standard seal material for shut-off couplers is Nitrile.
The electrohydraulic control mechanisms of the ME engine replace the following components of the conventional MC engine: Chain drive for camshaft Camshaft with fuel cams, exhaust cams and indicator cams Fuel pump actuating gear, including roller guides and reversing mechanism Conventional fuel pressure booster and VIT system Exhaust valve actuating gear and roller guides Engine driven starting air distributor Electronic governor with actuator Regulating shaft Engine side control console Mechanical cylinder lubricators.
