Abstract
A drain assembly adapted for use on a vehicle includes a drain chamber having upper and lower ends each having an aperture formed therein. The aperture in the upper end is sized larger than the aperture in the lower end. When a pressure differential exists between the two apertures and liquid is present in the drain chamber, a portion of this liquid will be retained in the chamber to create a fluid seal. The drain chamber itself may be constructed of various sections that are connected together and which may be readily separable in order to clean any debris that may collect within the chamber.
Claims9
A drain assembly adapted for use on a vehicle having an enclosed volume comprising:
- a generally vertically oriented drain chamber having an upper end and a lower end, said drain chamber comprising an elongated tube having upper and lower end plates fixedly secured thereto;
- first aperture means in communication with a first pressure zone for admitting a liquid into the chamber formed in said upper end;
- second aperture means in communication with a second pressure zone for draining liquid from the chamber formed in said lower end;
- said first and second aperture means and said drain chamber arranged to normally convey liquid without substantial interruption between said first and second pressure zones, said first and second aperture means being formed in said upper and lower end plates, respectively;
- said first aperture means being sized larger than said second aperture means such that when a predetermined pressure differential exists between said first and second aperture means with liquid in the drain chamber, said pressure differential will retain at least a portion of the liquid in the chamber to thereby maintain a liquid seal between said first and second aperture means.
A drain assembly adapted for use on a vehicle having an enclosed volume comprising:
- a generally vertically oriented drain chamber having an upper end and a lower end, said drain chamber including at least two sections;
- means for detachably securing said at least two sections of said drain chamber together;
- first aperture means in communication with a first pressure zone for admitting a liquid into the chamber formed in said upper end;
- second aperture means in communication with a second pressure zone for draining liquid from the chamber formed in said lower end;
- said first and second aperture means and said drain chamber arranged to normally convey liquid without substantial interruption between said first and second pressure zones;
- said first aperture means being sized larger than said second aperture means such that when a predetermined pressure differential exists between said first and second aperture means with liquid in the drain chamber, said pressure differential will retain at least a portion of the liquid in the chamber to thereby maintain a liquid seal between said first and second aperture means.
