Abstract: A fluid end with an internal bellows can be used in high pressure environments. The bellows is disposed within a plunger bore, and has an interior isolated from a working chamber of the fluid end. An end of a plunger is received in the interior of the bellows. The bellows contains an incompressible fluid at a constant volume. As the plunger extends into the interior of the bellows, the fluid it contains is displaced. Such fluid displacement causes the bellows to extend. As the plunger is retracted, the fluid replaces the volume formerly displaced by the plunger, and causes the bellows to accordion to a retracted position.

CPC classification number: F16K15/03

Abstract: A check valve with a flapper for directing high pressure abrasive fluid away from its sealing face. The check valve has a flapper which opens when fluid travels from an inlet to an outlet. The flapper closes when fluid flow stops or reverses by sealing a flat sealing face to a seal formed in a shoulder face of the valve. A surface feature protrudes from near the flat sealing face and forms a slanted face opposed to the direction of flow through the valve. This slanted face interfaces with fluid flow to more easily open the valve and directs flow away from the sealing face to reduce wear.
