Abstract
A system and method for sealing a pressure area in a washer pump is disclosed. The system and method provides designed interference and contact points between a plurality of adjacent walls which are arranged to define a serpentine channel and which are integrally molded into a pump housing and a motor housing. At least one of the plurality of walls becomes biased in response to fluid pressure in a pressure area such that it engages one or more of the plurality of walls in the mating housing to provide at least one seal to seal the pressure area. The walls may be provided with a beveled edge to facilitate providing a 'point contact' to enhance sealing. The system and method reduce or entirely eliminate the need for an O-ring between, for example, the pump housing and the motor housing.
