be used as a damper the sidewall 46 34 also defines at least one orifice 50 34 that provides a passageway for ingress and egress of air to the cavity 48 34 during a change in volume of the first cavity 48 34 and middle portion 44 34 the orifice 50 34 may be eliminated in those applications requiring only stiffening of the suspension the orifice meters the air so that the resiliency of the snubber middle portion 44 34 is greater for low frequency excursions than for high frequency excursions to thereby function as damper for low frequency excursions and as a gas spring for high frequency excursions the sidewall 46 34 may be thickened around the orifice 50 34 for reinforcement the orifice may be fitted with or formed with a nipple 52 34 for directing the air in a preselected direction or to a preselected location such as to an out of balance load sensor which shuts down the washer during certain conditions preferably the snubber has a box configuration and the sidewall has folds like a fan or like the bellows of an accordion to easily accommodate the change in volume operation of the present invention is believed to be.
