<p>PCT No. PCT/EP83/00340 Sec. 371 Date Aug. 10, 1984 Sec. 102(e) Date Aug. 10, 1984 PCT Filed Dec. 15, 1983 PCT Pub. No. WO84/02546 PCT Pub. Date Jul. 5, 1984.A tube separator (1) is provided comprising a housing (2) with inlet connection (13) and outlet connection (14) and a member (37) being disposed within the housing (2) and slidable between a first and a second end position. The member (37) comprises a channel (49) extending from an entrance opening (55) to an exit opening (56) and an area (40') on which the pressure in the inlet connection may act upon. Furthermore, a spring (46) acts upon the member (37) in a direction opposite to the action of the inlet pressure. The channel (49) forms a connection between the inlet connection (13) and the outlet connection (14) in the first end position of the member (37), and the member (37) separates the inlet connection (13) from the outlet connection (14) in the second end position of the member (37). The entrance opening (55) and the exit opening (56) each comprise a straight secant, and their respective secants being parallel to each other. Since the member (37) is displaced in a direction parallel to the secants (95, 96) the volume ventilated when the member (37) is displaced can be kept as small as possible.</p> |
