ABSTRACT:
A miniature valve for very small animals such as tiny weanling mice consisting briefly of a housing having an interior passage. A lever arm extends through the passage and slightly beyond the end of the housing so that the animal can move the lever by biting it with its teeth or deflecting it with its tongue. Deflection of the valve arm causes a valve head member to pivot and partially lift off a valve seat. The valve seat is of resilient material and formed at an angle to the underside of the valve head so that a "line-point" type contact is made between the valve head member and the valve seat. A biasing member, such as a spring, returns the lever arm to a centered position when the animal lets go of the lever thereby automatically preventing further water flow.
