Abstract

A working fluid casing includes a casing and a ventilation device. The ventilation means includes a ventilation channel located in a groove formed in the housing. The present application relates to venting devices and more particularly, but not exclusively, to venting devices that allow for reduced intrusion of foreign fluids or particles.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application No. 61 / 701,268, filed September 14, 2012, entitled Ventilation Device, which is incorporated herein by reference. technical field [0003] The present application relates to ventilating devices and more particularly (but not exclusively) to ventilating devices which provide reduced intrusion of foreign fluids or particles. Background technique [0004] Breathers are used in a wide variety of applications. For example, in a truck blower, a breather is provided in the oil-filled cap to cover the oil-filled passage and prevent pressure build-up in the oil tank, gear housing or the like due to temperature rise therein. The breather exhausts gas that has accumulated in the tank or the like. Some applications may experience environments where the breather is exposed to external high pressure foreign fluids. For example, in the case of a truck blower,...
