| 060453000 | With means purging, cleaning or separating undesirables from motive fluid | 6 |
| 20100186403 | Step-less hydrostatic gear box for rotary movement SLGB - The hydrostatic system for the step less rotary movement transmission contains two hydrostatic motors with radial pistons ( | 07-29-2010 |
| 20110067392 | BREATHER WITH INDEPENDENT INLET/OUTLET FLOW PATHS - The present invention provides an apparatus and method for filtering fluid in a breather assembly and providing uncontaminated fluid to a reservoir. The breather allows in-take fluid traveling through a first flow path to be filtered before entering the reservoir through a first directional valve. The breather also allows exhaust fluid traveling through a second flow path, separate from the first flow path, to exit through a second directional valve. | 03-24-2011 |
| 20140174070 | LIQUID AND AIR SEPARATOR - A liquid and air separator includes a housing having a sloped floor and a domed roof, an adaptor, a spacer, a deflector having a plurality of perforations thereon, and a plurality of breathers, each of the plurality of breathers having a stepped portion. | 06-26-2014 |
| 20140230424 | HYDRAULIC SYSTEM WITH SUCTION/RETURN FILTER - The invention relates to a hydraulic system, preferably for piloting and actuating a two-cylinder thick matter pump. The hydraulic system comprises a tank ( | 08-21-2014 |
| 20150089936 | AIRCRAFT HYDRAULIC SYSTEM - An aircraft hydraulic system for operating a plurality of hydraulically-operated actuators in the aircraft having a hydraulic reservoir in which hydraulic fluid is stored, a hydraulic distribution system coupling the hydraulic reservoir to the actuators and having a main flow line coupled to the hydraulic reservoir, a hydraulic pump fluidly coupled to the main flow line and the hydraulic reservoir to pump hydraulic fluid from the reservoir to the main flow line, a main filtration system fluidly coupled to the main flow line upstream of at least some of the actuators, and a self-cleaning filter fluidly coupled upstream of the main filtration system. | 04-02-2015 |
| 20150354609 | HYDRAULIC FLUSHING SYSTEM AND METHOD - A hydraulic flushing system comprises a hydraulic machine including a case drain, a gearbox having a cavity, and a flushing valve. The case drain is included in a hydraulic pump or a hydraulic motor. The flushing valve is fluidly connected to the case drain, fluidly connected to the cavity, and fluidly positioned between the case drain and the cavity. The flushing valve is configured to selectively allow hydraulic fluid to flow from the case drain to the cavity. | 12-10-2015 |
