Abstract:
1. An apparatus comprising: an elongate member; an actuation device that moves the elongate member, which is associated with the actuation device, away from the actuation device to an open position and toward from the actuation device to a closed position; and a valve body attached to the actuation device such that the elongate member is positioned within the valve body in which fluid that flows into the valve body from a fluid source flows out of the valve body when the elongate member is in the open position; the elongate member, positioned within the valve body, comprising a plug portion at one end of the elongate member, and associated with the actuation device such that the actuation device moves the elongate member linearly in a direction along an axis between the open position and the closed position; and the valve body comprising: a hollow portion; a connecting channel connected to the hollow portion and comprising a first diameter, the first diameter being constant; a second channel, connected at one end to the connecting channel and open at a second end, and comprising a diameter that expands from the first diameter to a second diameter, the second diameter being constant, and narrows from the second diameter to a third diameter, the third diameter being constant, such that the plug portion forms an interference fit with the connecting channel when the elongate member is in the closed position, the connecting channel being narrower than both the hollow portion and the second channel.
