Abstract
An eccentric rotary high pressure seal is disclosed herein. This seal includes a valve body and a spring located in a housing. The spring biases the valve body to rotate. The valve body defines a longitudinally extending passage having dimensions sufficient to allow an introducer needle to pass there through. This passage is offset from the axis of the valve body. The valve body is located in a housing that will allow the valve body to rotate therein. The housing defines two longitudinally aligned openings that are offset from the axis of the housing. These two longitudinally aligned openings are oriented such that the passage in the valve body can be aligned with the openings located in the housing. In this manner, an introducer needle can extend into the housing and hold the valve body against the bias of the spring. Once the introducer needle is removed from the housing, the valve body is no longer held in place against the force of the spring. Therefore, the spring causes the valve body to rotate within the housing so that the passage in the valve body is not aligned with the two longitudinally aligned openings formed in the housing. This prevents fluid flow through the housing past the valve body once the introducer needle is removed therefrom.
