ABSTRACT:
An impact and vibration resistent receiver dehydrator for use in a refrigeration or air conditioning system includes a body (10) enclosing a desiccant core (24). The core includes a projection (32) at a first end and a flat face (38) at a second end. The projection is nested in a resilient core support (50) which in turn is supported by a spring loaded baffle plate (56). The resilient core support is positioned in a recess (58) in the baffle plate. The baffle plate includes a radially extending flange (60) which serves to hold the baffle plate and first end of the core in fixed position relative to the interior of said receiver dehydrator body. The face of the second end of the core is supported by a perforated disc (42). A compressible filter pad (46) is positioned between the disc and the core. The filter pad wraps around the edge (40) of the core and serves to space and cushion the core from the interior of the body. The resilient core support and baffle plate serve to distribute the force of impacts to the body and cushion the core at the first end. The filter pad also serves to catch any fragments of the core and prevent them from escaping from the receiver dehydrator in the event the core is fractured.
