Abstract
An apparatus can include a housing, a plunger configured to reciprocate along an axis within the housing, and an internal fluid chamber disposed in the housing. A valve, having a valve base and a deformable seal, can also be included in the apparatus. The apparatus can further include a seat having an aperture therein. The valve is configured to move into and out of contact with the seat when the plunger reciprocates within the housing, based upon a fluid pressure in the internal flow chamber. In addition, an outer diameter of the deformable seal of the valve is less than an outer diameter of the seat.
Claims16
An apparatus, comprising:
- a housing;
- a plunger configured to reciprocate along an axis within the housing;
- an internal fluid chamber disposed in the housing;
- a valve comprising a valve base and a deformable seal, the deformable seal comprises a first side, a second side, and a seal contact surface;
- and a seat having a first end, a second end, and an aperture therein, wherein the deformable seal contact surface is configured to move into and out of contact with the second end of the seat when the plunger reciprocates within the housing, based upon a fluid pressure in the internal flow chamber, wherein a diameter of the first side of the deformable seal is smaller than an outer diameter of the seat, and wherein the diameter of the first side of the deformable seal is greater than a diameter of the second side of the deformable seal, the first side of the deformable seal borders the seal contact surface, and the first side and the second side of the deformable seal are separate from the seal contact surface, and wherein an outside rim of the deformable seal is inwardly curved from the second side of the deformable seal to the first side of the deformable seal.
A valve assembly for a high pressure pump, said valve assembly comprising:
- a valve comprising a valve base and a deformable seal, the deformable seal comprises a first side, a second side, and a seal contact surface;
- and a seat having a first end, a second end, and an aperture therein, wherein when the valve is closed the seal contact surface is disposed on a contact surface of the second end of the seat, wherein a diameter of the first side of the deformable seal is smaller than an outer diameter of the seat, and wherein the diameter of the first side of the deformable seal is greater than a diameter of the second side of the deformable seal, the first side of the deformable seal borders the seal contact surface, and the first side and the second side of the deformable seal are separate from the seal contact surface, and wherein an outside rim of the deformable seal is inwardly curved from the second side of the deformable seal to the first side of the deformable seal.
A valve for a high pressure pump, said valve comprising:
- a valve base having a valve contact surface;
- a deformable seal disposed on the valve base, the deformable seal having a first side, a second side, and a seal contact surface, wherein the first side and the second side of the deformable seal are separate from the seal contact surface;
- wherein a diameter of the first side of the deformable seal is greater than a diameter of the second side of the deformable seal,
- wherein the first side of the deformable seal borders the seal contact surface, and
- wherein an outside rim of the deformable seal is inwardly curved from the second side of the deformable seal to the first side of the deformable seal.
