Embodiment Construction

[0019] The embodiments disclosed below are not intended to be exhaustive, nor are they intended to limit the disclosed content to the specific forms described in detail below. Specifically, the following examples are chosen for description so that others skilled in the art can utilize the enlightenment given by these examples.

[0020] see figure 1 , wherein an exemplary connector assembly 10 is shown. The connector 10 includes a first connector 12 connected to a second connector 14 . In one embodiment, the connectors 12, 14 comprise attachments. A face seal 20 , described below, provides a sealed engagement between the first connector 12 and the second connector 14 . The first seal 12 schematically includes a tube or conduit 26 having a bend 22 and a mating end 36 . The second connection piece 14 is schematically a fitting 14 comprising a tube or conduit 16 and a socket 24 at the mating end 34 of the fitting 14 . The second connecting part 14 may also include a connector...

Abstract

A vehicle is provided having a fluid connector assembly. The fluid connector assembly may include a face seal positioned between connectors. The face seal may include an o-ring having an asymmetrical outer profile. The face seal may include a top lobe, an outer lobe, and an inner lobe. The outer lobe may be positioned under a groove retaining lip of the connector assembly.

Description

technical field [0001] The present disclosure relates to an annular seal for a fluid connector assembly, and more particularly to a multi-lobed seal with an asymmetric cross-section for a fluid connector assembly in a vehicle. Background technique [0002] In hydraulic and pneumatic systems, pipe or hose connections often have a face seal between the connections. The face seal typically consists of a standard O-ring seated in one of the connector grooves. The connector may include a groove retaining lip for keeping the O-ring in place. Standard O-rings with a typically circular cross-section tend to slip out of the notch lip and pop out of the face seal groove. Not only that, but misaligned seals can become pinched between connectors, leading to potential damage to the seals. [0003] A failed seal at a pipe connection can result in leakage of hydraulic fluid. During agricultural and construction machinery applications, fluid leaks can contaminate the ground, causing tem...
