Abstract
A liquid drain (2) includes a drain body (20). The drain body defines a float chamber (30) that is adapted to store a liquid. A liquid level adjusting mechanism serves to adjust the liquid level within the float chamber and includes a float (40; 240; 340; 440; 540). The float has a float body (42; 242; 342; 442; 542) that is adapted to float on the liquid surface within the float chamber. A damper (43; 46; 243; 343; 443) may inhibit or minimize a shaking phenomenon of the float body due to waving of the liquid within the float chamber.
Claims22
A liquid drain comprising:
- a drain body defining a float chamber, wherein the float chamber is arranged and constructed to store a liquid,
- a liquid level adjusting mechanism arranged and constructed to adjust the liquid level within the float chamber and including a float, wherein the float includes a float body arranged and constructed to float on a surface of the liquid stored within the float chamber, and
- a damper arranged and constructed to inhibit or minimize the movement of the float body due to waving of the liquid within the float chamber.
A liquid drain comprising:
- a drain body;
- a float chamber defined within the drain body and arranged and constructed to store a liquid,
- a float having a float body, wherein the float body is arranged and constructed to float on a surface of the liquid stored within the float chamber,
- a valve arranged and constructed to open and close in response to the movement of the float body, wherein the valve opens to discharge a surplus amount of the liquid when the amount of the liquid stored in the float chamber exceeds a predetermined amount, and
- a damper disposed below a center of buoyancy of the float body and arranged and constructed to provide a damping effect for the liquid within the float chamber.
