摘要:
The invention relates to a device for purifying gas from a crankcase of an internal combustion engine, which comprises: a transfer wall (3) having a wall portion (12) with a least one narrow accelerated-distribution opening (14a); one gas-flow deflection wall (10) placed behind the transfer wall and defining an impingement and guide surface (20); an auxiliary opening (24) separate from the narrow opening, made in the transfer wall; and a bypass valve (15) movable to meet a return member (36) and provided to close the auxiliary opening (24) via a closure element (30) for moving closer to the surface (20), the return member (36) extending in the impingement chamber and having a portion (38) that pushes behind the auxiliary opening in the event of overpressure upstream of the transfer wall.
摘要:
A Diesel fuel filter (1) with interchangeable cartridge, which comprises a filtering mass or cartridge (2) which is contained within a container which has a side wall (3) and a bottom (4) and is provided with a lid (6) which is fixed detachably. The filter further comprises a duct (8) which is located in a peripheral region of the container and is suitable to connect a fuel intake connector (9) to a duct (7) which is formed within the lid (6) and is provided with passages (10) which open onto the portion of space (11) between the filtering mass (2) and the side wall (3) of the container, so as to allow the fuel to access the filtering mass (2), through which it flows from the outside inward. A fuel discharge connector (14) is furthermore provided at the bottom (4) of the container and is open in the central region of the portion of space delimited inside the filtering mass (2).
摘要:
The fuel filter (1) has an outlet for the filtered fuel in a lower base portion (BP) of a casing (2, 3), and a valve associated with said outlet. The filter insert (6) has an internal space in which filtered fuel flows and that accommodates a central member (32) capable of moving the valve (22) to an open position when the insert is in an operational configuration in the casing. The valve is urged, by default, to a sealed position cutting off the flow to the outlet, for example by resilient return means (R) arranged between the bottom (2a) of the filter and a wall (P) of an interface (17) that guides the lower end (32b) of the central member. The central member and the filter insert form a removable unit, and it is therefore possible, typically by means of a cover/removable unit fastening, to automatically obtain the sealed position after opening the top cover (3).
