Problems solved by technology

Such a configuration provides a secure fluid connection, but can require considerable connection time and tools (e.g., wrenches, etc.) for providing sufficient torque to tighten and unscrew the sleeve
Additionally, such mechanical linkages tend to be bulky and take up considerable volume, or are prone to failure

Embodiment Construction

[0037] figure 1A fluid coupling assembly 100 is shown comprising a first coupling member 102, a second coupling member 104, and a sealing member 110 disposed between the members. By virtue of the magnetic force provided by the first magnetic member 106 disposed on the first coupling member 102 and the second magnetic member 108 disposed on the second coupling member 104, the first coupling member 102 and the second coupling member 104 are held in mutual engagement. The first magnetic member 106 has a first polarity that is attracted to a second polarity of the second magnetic member 108 . The polarity of the first magnetic member 106 and the second magnetic member 108 may be permanent or induced. For example, the second polarity of the second magnetic member 108 may be generated by a permanent magnet or an induced magnetic effect.

[0038] In various embodiments, the engagement portion 112 of the first coupling member 102 comprises a size and shape that is complementary to ...

Abstract

Fluid coupling assemblies and methods are discussed. The fluid coupling assemblies include a first coupling member, a second coupling member magnetically engageable with the first coupling member, anda seal member disposed between a portion of the first coupling member and a portion of the second coupling member. A magnetic engagement of the first coupling member and the second coupling member unseals a fluid flow path therebetween. In certain examples, the first coupling member is sealed by a valve member and the second coupling member includes an activation member. When engaged, the valve member is moved from a closed position to an open position by the activation member, thereby unsealing the fluid flow path. A magnetic force between the first coupling member and the second coupling member can be chosen such that the members disengage when a predetermined fluid flow path pressure is reached.

Description

[0001] claim priority [0002] Priority is hereby claimed to U.S. Provisional Patent Application Serial No. 60 / 864,749, filed November 7, 2006, and U.S. Provisional Patent Application Serial No. 60 / 882,045, filed December 27, 2006, both of which All applications are incorporated into this specification by reference. technical field [0003] This patent document generally relates to a fluid coupling assembly for fluid transfer applications. More specifically, but not intended to be limiting, this patent document relates to magnetic fluid coupling assemblies and methods. Background technique [0004] Fluid couplings for fluid transfer applications typically include a sleeve having a fluid flow passage, and a plug also having a fluid flow passage. The sleeve is for example connected to the first fluid line and the plug is for example connected to the second fluid line. The plug is pushed into the socket to join the two lines, and then, at a later time, one or more valves are...
