Abstract: A valve gate piston assembly, in an injection molding system, is positioned in a staggered arrangement such that one piston assembly overlaps that of another valve gate piston assembly thereby minimizing an overall centerline pitch between said piston assemblies. Such a superposed layout of piston assemblies enables larger diameter pistons to occupy a smaller footprint than would be realized should the same piston assemblies be positioned side by side. The use of relatively larger diameter pistons results in an increased force available, for the same input air pressure, to actuate the pistons and valve stems attached thereto, resulting in a higher valve stem closing force. A staggered piston assembly layout also allows independent air circuits to control each piston separately. A combination of multiple piston assemblies may be configured in such a staggered, overlapping array.

Abstract: A method and apparatus for servicing a pressurized system is described. A purge fitting can be used to vent the pressurized system. Venting can release a gas, such as air, from the system. The pressurized system can be a climate control system (e.g., an air conditioning or refrigeration system), a brake system, a hydraulic system, or a service device for servicing a climate control system. The purge fitting allows air that may be trapped in the pressurized system to be vented by depressing a purge actuator, such as a purge button attached to the fitting. The air can be vented from an opening adjacent to the actuator or other orifice. By purging air directly from the system, the amount of air introduced into the system during servicing can be minimized. The invention also features a coupling member that can be compact in size.

The valving system diverts the fluid in a switchable manner that minimizes energy usage without diverting raw fluid directly to an output. A sealing system is located at the ends of the dampers.
