Patent number: 6789579Abstract: The present invention relates to a medium-carrying hose, preferably for pressure medium and for use in, for instance, an engine unit, the wall of the hose comprising at least one wall portion (5). The wall portion (5) is connected with at least one expansion portion (4) to form a continuous hose casing, so that the circumference of the hose is variable between a minimum value, when the expansion portion (4) is unexpanded, and a maximum value, when the expansion portion (4) is maximally expanded. The expansion portion (4) extends in the transverse and the longitudinal direction of the hose, the wall portions (5) being displaced relative to each other both in the transverse and in the longitudinal direction of the hose as the circumference increases and the expansion portion (4) expands. The invention also relates to a method for manufacturing such a hose.Type: GrantFiled: January 23, 2002Date of Patent: September 14, 2004Assignee: ABA of Sweden ABInventor: Morgan Ryhman

Patent number: 6467817Abstract: A device for connecting two rigid tubular objects, comprising a male part and a female part. The male part is provided with at least one transverse edge in its outer wall. A sleeve-shaped element is arranged to be placed between said parts when inserting the male part into the female part, the element being provided with at least one resilient tongue with a first member which is arranged to resiliently engage the recess of the female part when inserting the element into the female part, and a second member which is arranged to resiliently snap into place behind the transverse edge of the male part when inserting the male part into the element. The resilient tongue allows the female part and the male part to be separated by turning the element relative to the male part to a position where the second member of the resilient tongue is arranged laterally of the transverse edge of the male part and/or by moving the first member of the resilient tongue out of engagement with the recess of the female part.Type: GrantFiled: April 28, 2000Date of Patent: October 22, 2002Assignee: ABA of Sweden ABInventor: Morgan Rhyman

Patent number: 5988704Abstract: The invention relates to a hose coupling device, which comprises a male part connectable to a female part. The female part consists of a sleeve, which is provided with a number of resilient tongues extending in equally spaced relationship along the inner wall of the sleeve and protruding inwards form the inner wall and directed away from the mouth of the sleeve. The male part consists of a tube portion with transverse edges in its outer wall. At the insertion of the male part into the female part the resilient tongues are arranged to resiliently snap into place behind the transverse edges of the male part and hence connect the female part to the male part. The parts can be separated by turning them relative to one another to a position where the resilient tongues assume a position laterally of the transverse edges.Type: GrantFiled: July 2, 1998Date of Patent: November 23, 1999Assignee: ABA of Sweden ABInventor: Morgan Ryhman

Patent number: 5720086Abstract: A clamping collar for sealing by perimetrically connecting the axially aligned ends of two parts which are circular in external transverse cross-sectional shape. The collar includes a strip formed into an open loop, V-shaped in longitudinal section, having two circumferentially opposite ends, and a tightener for extending force on the ends for circumferentially tightening the collar on the ends of the two parts. The tightener includes a separator for separating the two ends when the collar is loosened, for facilitating the opening and removal of the collar from the parts.Type: GrantFiled: October 2, 1996Date of Patent: February 24, 1998Assignee: ABA of Sweden ABInventors: Roger Eliasson, Morgan Ryhman, Philippe Bechler

Patent number: 5671506Abstract: A hose clamp including a band having end portions extending in an overlapping relationship through a housing. One end portion is secured to the housing while the opposite end portion is arranged for displacement through the housing. The housing encloses a screw mechanism with a screw worm in engagement with a row of gear teeth formed in the displaceable end portion of the band and by which the hose clamp may be tightened about an object.Type: GrantFiled: June 10, 1996Date of Patent: September 30, 1997Assignee: ABA of Sweden ABInventor: Roger Eliasson

Patent number: 5630255Abstract: The invention concerns an improved hose clamp consisting of an outer annular tightening band (1) which is provided with a tightening device (3, 4), and of a resilient band (2) which extends along the inner face of the tightening band (1). The resilient band is provided with two axially spaced, inwardly directed peripheral beads (6) which extend around the resilient band (2). Intermediate the beads (6) the resilient band (2) is formed with an outwardly directed ridge (7) in abutment against the inner face of the tightening band (1). By means of a number of openings (8), the ridge (7) is divided into a number of bridges (9) which interconnect the beads (6) with one another around the resilient band (2). These bridges (9) are arranged to allow bead movability in the radial as well as axial directions.Type: GrantFiled: June 6, 1996Date of Patent: May 20, 1997Assignee: ABA of Sweden ABInventor: Roger Eliasson
