  • Patent number: 6315330
    Abstract: Liquid dispensing apparatus having a pressure loaded quick disconnect assembly. The apparatus includes a first liquid containing component having at least one liquid passage, a second liquid containing component including at least one liquid passage, a movable connecting member having portions contained in the passages of the first and second liquid containing components, and a force transmitting member connected with the movable connecting member. The force transmitting member directs force against the first liquid containing component when the liquid passages of the first and second liquid containing components contain the pressurized liquid. This securely connects the first and second liquid containing components together using force generated by the internal pressurized liquid. When the pressure is removed, the force transmitting member may be quickly removed to disconnect the components.

  • Patent number: 6257627
    Abstract: A tube to be connected to a pipe is formed of a base portion, a wide portion and a narrow portion integrally molded together. The wide portion has an inner end extending to the base portion, and an opening formed at a side opposite to the inner end. An inner diameter of the wide portion is greater than that of the base portion. When the pipe is inserted, the base portion receives an insertion portion of the pipe, while the wide portion receives a projecting portion of the pipe therein. The narrow portion deformably projects inwardly from an inner circumference of the wide portion at a position away from the inner end. The narrower portion allows the projecting portion to pass therethrough in a pipe inserting direction by deformation thereof, and prevents the projecting portion from passing therethrough in a pipe removing direction opposite to the pipe inserting direction.

  • Patent number: 6113151
    Abstract: A high pressure quick connector is disclosed for use in connecting brake lines of a vehicle, particularly to a brake junction for an anti-lock brake system. The connector includes a housing for receiving a tube retainer. The tube retainer has a lower cylindrical portion that is positively attached to enclose a flared end form to provide a fluid seal. Retaining means in the form of a snap ring works in conjunction with a pop top to provide a low force and a positive insertion indicator. The snap ring has ears that are compressed together and inserted up inside a slot in the pop top. Upon installation of the tube retainer and retaining means into a central bore of the housing, an end portion of the housing makes contact with the pop top so that the pop top slides up the tube. As the pop top slides up the tube, the snap ring ears are released from the pop top slot. The snap ring expands upon release into a final latching position with the housing and tube retainer.

    Abstract: A quick connect-disconnect fluid coupling assembly having cylindrical outer and inner coupling members, one of which is connected to a conduit and the other to a fluid conveying system. The assembly is accomplished by inserting a U-shaped locking member having a bight and two parallel legs into the outer member, which has a peripheral groove receiving the bight so that the curved portion thereof does not extend beyond the periphery. Slots in this member receive the legs, which are then locked around grooves in the inner member and the ends of the legs do not extend beyond the periphery of the outer member. The outer portion of the bight is thinner than the inner portion to permit easy insertion into, and withdrawal from, the groove of the outer member. The system may also be utilized in an assembly of three or more components, wherein two or more locking members are used.

  • Patent number: 5961159
    Abstract: A first quick-coupling part can be brought into interaction with a second quick-coupling part via an interaction portion. The quick-coupling parts are held together with locking members. The interaction portion is designed with a surface layer which brings about an essentially crack-free flexibility for the locking members in spite of high actuating forces. One or more underlying layer(s) has (have) greater hardness than the surface layer, and the combination of said layers gives the necessary resistance against high media pressure.

  • Patent number: 5951064
    Abstract: An array of a plurality of module blocks with a common through-passageway with a combined fluid coupling and mechanical connector fitting received in the passageway between each pair of adjacent blocks. The fitting has a swivel body rotatably retained by a flexible retaining wire on a main body with two static-type O-rings. The main body has external straight threads on one end and a hex head protrusion adjacent the other end. A fluid conducting through-passageway in the main body has an enlarged cylindrical counterbore open at the hex end and with a circular internal groove therein. A tangentially intersecting wire-insertion radial opening leads from an external surface of the hex head into this groove. The swivel body has external straight male threads at one end, a cylindrical shank at the other end and a fluid conducting through-passageway communicating at one end with the main body passageway and having a hex socket in the other passageway end.

  • Patent number: 5927763
    Abstract: A method for connecting a first end of a cylindrical pipe of given external diameter within a bore of a pipe element having a terminal portion with an internal diameter sufficient to receive the first end, includes outwardly deforming a part of a wall of the terminal portion of the pipe element so as to define an approximately linear open ended channel in a direction roughly tangential to the internal surface of the terminal portion. The first end of the pipe is then positioned within the terminal portion and a pin-like element is forced along the channel. This causes local inward deformation of the first end, thereby locking the first end and the pipe element together. Preferably, an additional part of the wall of the terminal portion is deformed outward to form an annular recess around the interior of the terminal portion for receiving a sealing element.

  • Patent number: 5904221
    Abstract: In a toothed-rack power-assisted steering, which is provided for motor vehicles in particular, a pinion (2) seated in a steering housing (1) is in engagement with a toothed rack (6). A servo motor (8) is disposed as a power assist, whose piston rod (10) is drivingly connected with the toothed rack (6). The two work chambers (12, 13) of the servo motor (8) are connected with a control device (18) via work lines (12, 13), which are connected with a cylinder (11) of the servo motor (8) and with the control device (18) via two connecting elements (24, 25). Each work line (14, 15) has a collar (32). Each line is held on the connecting element (24, 25) by a fastening clasp (34) which projects over the collar (32). The fastening clasp (34) has an essentially rectangular and flat base (35). An elongated slit (36), open toward one side, is located in the base (35), through which the fastening clasp (34) can be pushed from the side over the line (14, 15) and the connecting element (24, 25).
