Abstract
A flow stopper has an elongated shape for positioning in a tubular cavity of a check valve. The elongated shape has a concave section such that the flow stopper can impact a line running along an inner surface of a housing forming the tubular cavity in a lengthwise direction of the tubular cavity. The concave section allows the flow stopper to impact the housing with a first point of contact and a second point of contact on the line, and the two points of contact are separated by a gap where the flow stopper does not contact the housing. The flow stopper may include a first and a second ball where the balls are connected by a stem. The flow stopper may also include a plurality of balls that are not connected to each other. The flow stopper may include a ball connected to a stem.

A flow stopper for controlling fluid flow within a tubular cavity formed by a housing of a check valve, wherein:
- the flow stopper is moveable between a first position and a second position within the tubular cavity;
- the flow stopper in the first position is adjacent to a seat of a bottom port of the housing thereby obstructing fluid flow through the bottom port;
- the flow stopper in the second position is away from the seat of the bottom port thereby allowing fluid to flow through the bottom port;
- the flow stopper has an elongated shape;
- and
- the elongated shape has a concave section such that the flow stopper can impact a line running along an inner surface of the housing in a lengthwise direction of the tubular cavity, the concave section allowing the flow stopper to impact the housing with a first point of contact and a second point of contact on the line, the concave section ensuring that the first point of contact and the second point of contact are separated by a gap where the flow stopper does not contact the inner surface of the housing on the line.
A check valve comprising:
- a housing forming a tubular cavity within the housing;
- and
- a flow stopper within the tubular cavity;
- wherein the flow stopper is moveable between a first position and a second position within the tubular cavity;
- the flow stopper in the first position is adjacent to a seat of a bottom port of the housing thereby obstructing fluid flow through the bottom port;
- the flow stopper in the second position is away from the seat of the bottom port thereby allowing fluid to flow through the bottom port;
- the flow stopper has an elongated shape;
- and
- the elongated shape has a concave section such that the flow stopper can impact a line running along an inner surface of the housing in a lengthwise direction of the tubular cavity, the concave section allowing the flow stopper to impact the housing with a first point of contact and a second point of contact on the line, the concave section ensuring that the first point of contact and the second point of contact are separated by a gap where the flow stopper does not contact the inner surface of the housing on the line.
