Publication number: 20100133457Abstract: The invention relates to a coaxial coupling which comprises a male part (501) and a female part (502) and comprises a bypass valve (218) so that the female part (502) can be decoupled from the male part (501) while pressurized fluid passes through the female part (502). The nipple pipe (105) of the male part (501) pushes a spring-loaded valve (218) in the female part (502) over said rear holes (301) in the inner pipe (2) of the female part. The female part (502) has a rotatable locking sleeve (207), which is coupled to a sleeve (214) accommodating pins (213).Type: ApplicationFiled: April 15, 2008Publication date: June 3, 2010Applicant: Bo Erik NybergInventors: Jörgen Ekström, Lars-Erik Svensson

Publication number: 20090051161Abstract: Multiconnector for hoses (9) or the like for media under pressure, comprising a first and a second connection element (3?, 3?); the multiconnector (1) comprises first and second male parts (21?, 21?) and first and second female parts (23?, 23?); one of the connection elements (3?) comprises a female part (23?) that comprises a locking sleeve (17), that is spring-loaded towards a locked position, in which position the locking sleeve (17) holds a ball catch (52) in an engaged position for locking the male part (21?) in the female part (23?) in a connected position; the locking sleeve (17) can be moved against the spring-loading in a direction (p) away from the male part (21?) for releasing the first connection element (3?) from the second connection element (3?). The locking sleeve (17) of the female part (23?) is associated with an operating device (29) for the said releasing.Type: ApplicationFiled: January 31, 2007Publication date: February 26, 2009Applicant: Bo Erik NYBERGInventor: Jorgen Ekstrom

Patent number: 6279874Abstract: A coupling for connecting hoses to a medium under pressure includes a female part having a nipple release mechanism and at least one ball-type nipple locking member for initially locking a nipple in place within the female part, an axially displaceable valve member centrally located and movable in the female part from a closed position in contact with an annular valve seat and an open position away from the valve seat, a nipple insertable in the female part and having a groove in an outer surface region thereof adapted to initially engage the ball-type nipple locking member for locking the nipple in place in the female part upon insertion.Type: GrantFiled: December 17, 1998Date of Patent: August 28, 2001Assignee: Bo Erik NybergInventor: Kent Nyberg

Patent number: 6082399Abstract: The invention relates to a quick coupling for hoses or pipes for pressure media, especially for hydraulic media under high pressure. The coupling comprises a female part (1) and a nipple (2), said female part (1) having a displaceable valve element (4), which, in the decoupled state lies in sealing contact against the female part (1) by means of a sealing ring (5) and has an extension (7) with an enlarged end piece (8). The nipple has a displaceable valve element, which in the decoupled state, seals against the nipple (2) by means of a sealing ring (19). According to the invention, the valve element (4) of the female part (1) has, about its extension (7), an axially displacable tube (9) which is urged by its spring (11) towards a position in abutment against the end piece (8). The tube (9) has essentially the same outer diameter as the valve elements (4, 18).Type: GrantFiled: November 23, 1998Date of Patent: July 4, 2000Assignee: Bo Erik NYBERGInventor: Kent Nyberg

Patent number: 5123448Abstract: A valve arrangement for a pressure fluid, particularly high-pressure oil, has a valve housing (10, 90, 190) with an internal, cylindrical sealing surface (16, 100, 160) which forms a guide for the outer, cylindrical sealing surface (42, 107, 162) of a piston body (18, 106, 138). There is provided a circular groove which accommodates a sealing ring (46, 64, 108, 164). An axially displaceable valve sleeve (30, 70, 122, 156) is disposed coaxially with the two cylindrical sealing surfaces(16, 42, 100, 107, 162, 160) and has a cylindrical valve-sealing surface (40, 74, 124, 158). This valve sleeve is biased by a spring (34, 80, 118, 172) such that one end (36, 82, 126, 174) abuts substantially sealingly a seating (38, 86, 128, 176) at that end of the sealing surface such as to form a closed gap (41, 86, 130, 178) at one end of a channel (32, 73, 132, 145).Type: GrantFiled: July 16, 1991Date of Patent: June 23, 1992Assignee: Bo Erik NybergInventors: Kenneth Kjellberg, Ake Jonsson
