20080224353 | Hydraulic Valve of Molding System - Disclosed is: (i) a molding system having a hydraulic valve, (ii) a molding system having: (a) an extruder, (b) a hydraulic circuit, and (c) a hydraulic valve, (iii) a hydraulic valve of a molding system, (iv) a method of a molding system having a hydraulic valve, and (v) a valve controller performing a method of a molding system having a hydraulic valve. The hydraulic valve includes: (i) a valve sleeve that is configured to convey a pressurized hydraulic fluid, and (ii) a valve spool that is movable relative to the valve sleeve, once the valve spool is made to move from a valve-closed position to a valve-opened position, the valve spool is imparted with a running start before the pressurized hydraulic fluid is permitted to flow out of the valve sleeve. | 09-18-2008 |
20080210720 | Check Valve with a Spiral Coil Seal - A seal for a check valve for a metal molding machine. The seal is provided by the combination of a peripheral groove in an outer surface of the check valve and a helically wound core in the groove. The helically wound coil is expandable into sealing engagement with a cylindrical wall of the molding machine. The helically wound coil may be movable laterally in the groove between a melt channel open position and a melt channel closed position to open or seal the melt channel. | 09-04-2008 |
