摘要： An improved unloader valve assembly for a high-speed reciprocating compressor includes improved poppets and valve seat designs. The improved poppets and valve seats are useful for reducing or eliminating poppet leakage and high impact stresses on the sealing surfaces of the poppets, and are especially intended for use with high-speed reciprocating compressors operating at 1000 rpm and higher. A control chamber spacer plate for creating a control pressure chamber within the unloader valve assembly, and a valve seat cushioning plate for reducing stress on the head ends of the poppets are also described.

摘要： Apparatus and method contemplating a high pressure fluid end assembly having a body defining a body bore and defining a recess in the body intersecting the body bore. A closure is joined to the body and forms a sealing surface. A seal is mounted to the body in the recess and configured to extend from the recess beyond the body bore to seal against the sealing surface formed by the closure.

摘要： A variable flow rate valve mechanism of the present disclosure includes a stem which is rotatably supported by a housing, a bearing which is inserted through a through-hole of the housing and supports the stem to be rotatable about an axis of the stem, and a valve portion which is provided at one end side of the stem and covers an opening. The stem is disposed so that the axis of the stem crosses the opening. The valve portion rotates about the axis of the stem and opens and closes an opening of a variable gas flow rate passage.

摘要： A seal for a plug valve and method for manufacturing a seal. The seal includes a sealing element, and a back-up ring coupled with the sealing element by an interference fit. When the back-up ring and the sealing element are coupled together, the back-up ring and the sealing element are curved about a first axis and about a second axis.
