20140261718 | MAIN STAGE IN-LINE PRESSURE CONTROL CARTRIDGE WITH OPTIONAL REVERSE FLOW FUNCTION - A main stage in-line pressure control cartridge. The cartridge selectively controls flow in-line in the same direction as opposed to directing flow at a 90 degree angle like other cartridges. A tubular poppet can be mounted into a body and has a sliding control sleeve that can expose radial holes in the poppet to an open position and to seal the radial holes in a closed position. The cartridge can be configured in numerous ways in order to serve many functions, such as a pressure relief valve, a counterbalance valve, and a flow control valve. The cartridge can also be configured to allow or prevent reverse flow. | 09-18-2014 |
20150152895 | CYLINDER PHASER VALVES - A phaser valve for a piston and cylinder assembly helps to keep a pair of pistons in phase with each other. The phaser valve includes a poppet which is slidable between opposing seats of a valve housing. The poppet includes a head and a stem, both the head and the stem having concave portions which facilitate the flow of hydraulic fluid across the valve. The poppet head has two generally conical ends, so that the head makes a fluid-tight seal with a seat when the head is urged towards either seat. Due to its construction, the phaser valve may be built to fit within a very small space, while still allowing a substantial flow of fluid when the head is not in abutment with one of the seats. | 06-04-2015 |

20090000679 | MECHANICAL FASTENING AND LOCKING OF STRUCTURAL, FLUID, AND ELECTRICAL COMPONENTS AND SYSTEMS - A stack or assembly of fluid, mechanical, and/or electrical components permits removal of some components for maintenance, without compromising the fluid integrity of the remainder of the assembly. A fastening bolt, attached to at least one fluid component, is screwed into a stacking bolt, attached to another fluid component, the bolts being screwed together inside the bore of an adapter plate. A resilient insert sits between the head of the stacking bolt and the bore. At least a portion of the bore has a continuous taper, such that the diameter of the bore decreases in the vicinity of the insert. The taper creates a reduced diameter hole on one surface of the adapter plate, thus preventing interference between fluid ports on an adjacent fluid component. The taper also prevents loss of the insert during transportation and storage, and prevents undesired extrusion of material of the insert when the components are fastened together. | 01-01-2009 |
