  • Publication number: 20160010605
    Abstract: A filter (10) with a filter element (36) are described. A housing (12) includes at least one fuel inlet, fuel outlet (18) and a water outlet (30) for water separated from the fuel. The filter element (36) within the housing separates the fuel inlet (26) from the fuel outlet (18). The filter element (36) includes a hollow body filter medium (38) flowed through radially. A water separation unit (56) with a hollow body hydrophobic fuel-permeable separating medium (66) separates water contained in the fuel and includes at least one support structure disposed in the flow path (78) in such a way that a precipitation gap (74) is realized between the filter medium (38) and the separating medium (66).

  • Publication number: 20160001205
    Abstract: The invention relates to a fuel filter (10) having a filter element (12) for separating water from the fuel. The water can be fed into a collection chamber (24) of the fuel filter (10) via a first conduit (26), which extends from the filter element (12) to the collection chamber (24). Provided in the first conduit (26) is a branching off of a second conduit (32), which enables fluid discharge from the first conduit (26). Preferably, a throttle (34) and in particular a press-fit throttle is provided in the second conduit (32), in order to regulate the amount of outflow. The second conduit (32) preferably branches off from the first conduit (26) at substantially a 90 degree angle to the first conduit (26), so that fluid flowing in the first conduit (26) primarily flows past the second conduit (32) and reaches the collection chamber (24).

  • Publication number: 20150122720
    Abstract: A water separating device of a filter element for separating water from a liquid hydrocarbon has a coalescing medium in the from of a hollow body and designed to coalesce water droplets of the liquid hydrocarbon passing through the coalescing medium in a flow direction of the liquid hydrocarbon. A hydrophobic separating medium in the form of a hollow body and permeable for the liquid hydrocarbon is provided. The hydrophobic separating medium is arranged in a flow direction of the liquid hydrocarbon downstream of the coalescing medium and separates water droplets of the liquid hydrocarbon from the liquid hydrocarbon. At least one precipitation gap is formed between the coalescing medium and the separating medium.

  • Publication number: 20150101975
    Abstract: A filter element arranged in a filter housing is provided with an annular filter medium flowed through by a liquid medium in a flow direction radial to a longitudinal axis of the filter element. A clean chamber is arranged in the flow direction of the liquid medium downstream of the filter medium. A filtered liquid medium outlet is fluidically connected to the clean chamber. A cylinder-shaped water separating screen is arranged in the clean chamber to separate water contained in the liquid medium. A water outlet opening fluidically connects the clean chamber to a water collecting chamber of the filter housing. A particle filter is arranged at the water outlet opening or arranged between the water outlet opening and the filtered liquid medium outlet of the filter element. The water outlet opening of the filter element is fluidically connected with the water collecting chamber of the filter housing.

  • Publication number: 20150096290
    Abstract: A hydraulic system, preferably for actuating and engaging a mobile slurry pump, includes a primary circuit, actuating a first hydraulic consumer, which circuit has a hydraulic drive assembly including at least one motor-driven hydraulic pump. The hydraulic system further includes a secondary circuit, actuating a second hydraulic consumer, which circuit has a second hydraulic drive assembly including at least one additional motor-driven hydraulic pump. In a first operating state, hydraulic oil from a common tank can be admitted to the hydraulic consumers arranged in the primary circuit and in the secondary circuit via the hydraulic drive assemblies thereof, independently of one another. In a second operating state, a portion of the hydraulic oil is supplied from the primary circuit to the secondary circuit to actuate the second consumer.

  • Publication number: 20140284263
    Abstract: A fuel filter has a housing with fuel inlet for fuel to be purified, fuel outlet for purified fuel, and water outlet for water separated from the fuel. A filter element is arranged in the housing and separates seal-tightly fuel inlet from fuel outlet. The filter element has a filter medium formed as a hollow body and flowed through from the interior to the exterior of the filter element or in reverse. A coalescing medium formed as a hollow body is arranged in a flow path of the fuel downstream of the filter medium for separating water from the fuel. The coalescing medium surrounds the filter medium or is arranged in the interior. The coalescing medium has at least one nonwoven layer that coalesces water and has a main orientation of fibers transverse to a main flow path of separated water downstream of the coalescing medium.
