Abstract
In a sterilizing container with a perforated zone which can be covered over in relation to the interior of the container by a filter designed so that it can be displaced and covered over, in order to improve the protection of the filter, on the one hand, and the sealing-off of a bypass under different operating conditions, on the other hand, it is proposed that force elements be used for displacing a covering disc of the filter and the filter itself which change the displacement forces acting on the covering disc and on the filter, respectively, as a function of the temperature.
Claims16
Filtering apparatus for a sterilizing container comprising:
- a filter chamber;
- a filter enclosed by said filter chamber and mounted for sliding displacement toward a sealing surface of said chamber;
- an input zone in said filter chamber for allowing the entry of a sterilizing medium into the chamber;
- an output zone in said filter chamber for allowing the exit of said sterilizing medium;
- a covering member mounted within said chamber between said filter and one of said input and output zones for sliding displacement toward said filter;
- wherein said covering member sealingly contacts a sealing portion of said filter and said filter sealingly contacts the sealing surface of said chamber in response to a displacement of said covering member and filter;
- means for biasing said covering member away from said filter element and said filter away from the sealing surface of said chamber to provide a filtered flow path between said input zone and said output zone;
- means, responsive to the displacement of at least one of said covering member and filter, for opening an auxiliary flow path between said input zone and said output zone while closing said filtered flow path when said covering member is in sealing contact with said filter and said filter is in sealing contact with the sealing surface of said chamber;
- and
- means responsive to a change in temperature for facilitating the displacement of said covering member into sealing contact with said filter and said filter into sealing contact with the sealing surface of said chamber.
