Abstract: The invention relates to a mechanical seal device (1), comprising a rotating slide ring (2) and a stationary slide ring (3) that define a sealing gap (4) in between them, a retaining ring (5) for retaining the stationary slide ring (3), a housing (6) with a side that is oriented towards a product side (13) and a side that is oriented towards an atmospheric side (14), and a clamping mechanism (8), wherein a clamp connection is formed between the housing (6) and the retaining ring (5) by means of the clamping mechanism (8), wherein the housing (6) has at least one through hole (60) that connects the side of the housing that is oriented towards the product side (13) with the side of the housing that is oriented towards the atmospheric side (14), wherein the clamping mechanism (8) has a screw bolt (80) and a clamping element (82), wherein the screw bolt (80) is arranged in the through hole (60) of the housing (6), and the clamping element (82) has a threaded opening (83) into which the screw bolt (80) is screwed,

Abstract: A vent assembly or breathing tube adapted to relieve pressure in an axle assembly or other gear housing. A vent tube may be disposed within a casing and terminates at an oblique or circular open end in a skirt portion of the tube. At least one hole may extend through the side of the casing to allow pressurized gases within the housing to escape through the vent tube via the oblique opening. The casing has a hole disposed at the bottom surface to allow the return of any lubricant which might enter the casing through the side hole. The side hole is preferably located on a side opposite the lubricant flow direction. The neck portion may be integrally formed with the top portion and skirt.

Abstract: The present invention is directed to a vent assembly or breathing tube adapted to relieve pressure in an axle assembly or other gear housing. A vent tube is disposed within a casing and terminates at a non-truncated oblique open end. At least one hole extends through the side of the casing to allow pressurized gases within the housing to escape through the vent tube via the oblique opening. The casing has a hole disposed on a substantially closed bottom surface to allow the return of any lubricant which might enter the casing through the side hole. The side hole is preferably located on a side opposite the side facing the oblique opening.
