Abstract: PROBLEM TO BE SOLVED: To provide an exhaust treating filter having an enhanced efficiency for arrangement. SOLUTION: The exhaust post-processing filter has a housing 22 between first and second ends 30 and 32 along the direction of an axis 28. The housing 22 has first and second ports 34 and 36 at the same first end. One of the ports is an inlet and the other an outlet. The housing 22 has an intermediate area 38 of a cross-sectional area A1 on the vertical plane of the axis 28 between the first and second ends. The intermediate area has an exhaust (catalytic) filter element 24 disposed therein to cover the cross-sectional area A1. However, a hollow portion 40 having a small cross-sectional area A2 is present inside, so the actual cross-sectional area A3 of the exhaust filter element is A1-A2. A transfer tube 26 communicates with the second port through the hollow portion. Exhaust flows through the exhaust filter element 24 between first and second side portions 44 and 46 in an axial direction 42 and flows through the transfer tube and the hollow portion in the opposite axial direction 48.

Abstract: PROBLEM TO BE SOLVED: To provide a fuel filter capable of filtering fuel, and discharging fuel additive agent into the fuel at a controlled speed. SOLUTION: This fuel filter includes fuel additive agent 42 to be discharged into fuel. A discharge speed to fuel is controllable. The fuel additive agent 42 is positioned inside an inner chamber 40 to be constantly fluid-communicated with fuel in the filter through an opening part limited by a baffle plate 50 and/or a diffusion orifice 44. In a modified example, the opening part after the inner chamber can be controlled by a thermostat for limiting flow of fuel to the fuel additive agent 42. In the mode of the modified example, the fuel additive agent can be discharged substantially at a constant speed for uniformly maintaining the level of the fuel additive agent in the fuel. In this invention, a fuel filter of a longer life than a fuel filter representatively used in a fuel engine can be provided.

Abstract: PROBLEM TO BE SOLVED: To provide a system of controlling flow of fluid. SOLUTION: A system 20 includes two filters 30a, 30b, and an electric switching valve 34. A fluid fed into the system 20 flows via the switching valve 34 into either of the filters 30a, 30b. When fluid temperature is not less than a predetermined level, a control device 50 determines a position of the switching valve 34 on the basis of a measured value for downstream pressure of the filters 30a, 30b so as to feed the fluid into the particular filters 30a, 30b. Also, the control device 50 includes proximity switches 60a, 60b so as to determine whether the particular filters 30a, 30b are coupled to a body 32 or detached therefrom via the proximity switches 60a, 60b. Various fuel heaters 74 can be provided for heating fuel.

Abstract: PROBLEM TO BE SOLVED: To provide a ventilation system for a closed type crank case which adopts vacuum assistance from an inlet of a turbocharger for the suction of blowby gas. SOLUTION: A coalescer/filter 26 is arranged in a system 10 for filtering and removing oil particulates floated in a blowby gas. An escape valve 34 is also arranged for avoiding occurrence of excessive pressure inside a crank case due to clogging of the coalescer/filter 26 and fatal failure of an engine 12. A vacuum limitter valve 36 is arranged for preventing excessive lowering of absolute pressure of assisting vacuum generated by an air inlet 24 continued from a turbocharger 14, and preventing unevenness of pressure across a seal of the turbocharger 14. A bypass valve 32 is arranged for bypassing the blowby gass and keeping it away from the coalescer/filter 26 when pressure inside the crank case is excessively high.

SOLUTION: This fluid filter assembly 40 comprises an outer casing 41 containing a filter medium 42 and a center pipe 45 and end part caps 43, 44 in both end parts of the outer casing 41. Moreover, a molded nut plate 46 is fixed in the other opened end of the outer casing and the nut plate 46 is made of glass-reinforced fibers to be an integrated member and is provided with a nipple 59 to which an approximately cylindrical female screw forming a flow outlet 52 is attached. A base part defined by the bottom wall 60 and side walls 62 is unitedly connected to the nipple 59. U-shape grooves 63 to receive the tightly sealing compression gasket 47 are formed in the uppermost part of the side walls 61 and the outermost side parts 62 and a plurality of flow inlets 64 parted from one another are formed in the side walls 61.

Abstract: PURPOSE: To provide a filter capable of decreasing piping, reducing power loss and being efficient by a simple constitution. CONSTITUTION: A filter head 21 forms a flow path extending from a flow inlet 30 to a flow outlet 37 by incorporating into a filter body. A combined full flow filter element 23 and bypass filter element 24 is positioned in the filter body 24 to dispose in the flow path. The bypass filter element 24 provides further an exit flow conduit 25 with an exit opening. And a flow nozzle 26 is arranged so as an oil flow, which pass through the full flow filter element 20 and the bypass filter element 24 to the flow outlet 37, to pass through the flow nozzle, to form a flow pressure zone and to position the outlet opening of the exit flow conduit 25 in the low pressure zone.

Abstract: A channel filter is provided by corrugated fluted flow channels folded back and forth transversely to the pleats. Fluid moves along an axial flow direction from upstream to downstream in a housing. Initially, a sheet of filter media is corrugated in a serpentine sinusoidal pattern along a set of pleat bend lines. The bend lines extend axially to form axially extending fluted flow channels. The sheet then ha a plurality of creases or folds formed laterally across the pleat bend lines, and the sheet is then folded back and forth upon itself along plurality of runs.
