Abstract:
1. A high-pressure fluid pump operable to pressurize a fluid, the pump comprising: a hollow stud including a first end, a second end, and a cylindrical space extending axially between the first end and the second end; a housing fixedly coupled to the first end of the hollow stud; a high pressure cylinder disposed within the cylindrical space of the hollow stud, the hollow stud not inhibiting axial movement of the high pressure cylinder within the cylindrical space, the high pressure cylinder including a bore that extends from a first end to a second end of the high pressure cylinder, the hollow stud having a wall thickness that is substantially thinner than a wall thickness of the high pressure cylinder; a seal head engaged with the second end of the high pressure cylinder to define a seal therebetween; an end cap coupled to the second end of the hollow stud and the seal head, the end cap operable to apply an axial compressive force to the seal head to compress the seal head against the cylinder and to apply a tensile load axially to substantially the entire length of the hollow stud; and a plunger movable within the bore to pressurize the fluid in a space defined by the plunger, the seal head, and the high pressure cylinder.
