| 137513300 | With leak passage | 7 |
| 20090151798 | IRRIGATION SYSTEM EMITTER - The current invention provides a emitter with an internal passage for a drip irrigation system that delivers an irrigation fluid such as water from a fluid source to one or more plants. The emitter is capable of being operably attached to a tube or other conduit of an irrigation fluid. Optionally, the emitter includes a means for reversibly attaching a side portion of a tube to the emitter. | 06-18-2009 |

| 137513700 | Bypass in valve casing | 5 |
| 20110011468 | Check valve for abrasive blaster pressure vessel - A check valve is installed in the pressure flow line of an abrasive blaster of the type having a pop-up valve which opens under pressure and closes when depressurized to a predetermined level. The check valve is upstream of the pop-up valve and includes a having a valve chamber in communication with the pressure system for seating a valve mechanism adapted for opening and closing the valve chamber in response to the pressure level in the pressure system for closing the pressure system to back flow when the pressure in the system reaches a predetermined level. | 01-20-2011 |
| 20120266979 | Check Valve for Abrasive Blaster Pressure Vessel - A check valve is installed in the pressure flow line of an abrasive blaster of the type having a pop-up valve which opens under pressure and closes when depressurized to a predetermined level. The check valve is upstream of the pop-up valve and includes a having a valve chamber in communication with the pressure system for seating a valve mechanism adapted for opening and closing the valve chamber in response to the pressure level in the pressure system for closing the pressure system to back flow when the pressure in the system reaches a predetermined level. | 10-25-2012 |
| 20130199634 | CONTROL VALVE FOR HYDRAULIC MEDIA - A control device for hydraulic media with a control valve, in particular, a proportional valve that has a sleeve housing provided with radial openings, wherein at least one pressurized flow feed line, at least one control line, and at least one return line are connected to the openings, and the opening for the pressurized flow feed line is connected to a ring-shaped groove, with a control slide that has control edges and is supported in the sleeve housing so that it can move in the axial direction and is actuated by an electromagnetically constructed control unit, advantageously for controlling a phase adjustment device for the variable adjustment of the control times of gas exchange valves of a reciprocating piston internal combustion engine. A non-return valve is installed in the pressurized flow feed line or in the ring-shaped groove that is arranged in the sleeve housing. | 08-08-2013 |
| 20140060672 | PRESSURE-LIMITING VALVE - A pressure-limiting valve is proposed, in particular for a common rail system. The pressure-limiting valve comprises a valve support ( | 03-06-2014 |
| 20150101687 | Liquid Valve Design with internal Check Valve - A valve is provided including a valve body and a valve element arranged within the valve body. The valve body includes an inlet port, an outlet port, and an inner surface that defines a flow channel. The valve element includes a through passage and is configured to rotate between an open position and a closed position to control a flow of fluid through the flow channel. A check valve assembly is arranged within the valve element generally perpendicular to the through passage. The check valve assembly is configured to move between a first position and a second position in response to an increase in pressure when the valve element is in a closed position. | 04-16-2015 |
