Abstract
An example valve includes a housing, a sleeve disposed within the housing and having a first end and a second end opposite the first end, and the sleeve includes a plurality of sleeve protrusions at the first end and a plurality of fluid flow channels are formed between adjacent sleeve protrusions, a seal carrier disposed within the sleeve and having a carrier protrusion that extends from the second end of the sleeve and abuts against an interior surface of the housing, and an end cap mounted to the housing such that the plurality of sleeve protrusions abut against the end cap.
Claims20
A flow control valve comprising:
- a housing, wherein the housing comprises a first port;
- a sleeve disposed within the housing, wherein the sleeve has a first end and a second end opposite the first end, wherein the sleeve comprises a plurality of sleeve protrusions at the first end and a plurality of fluid flow channels are formed between adjacent sleeve protrusions;
- a seal carrier disposed within the sleeve, wherein the seal carrier comprises a carrier protrusion that extends from the second end of the sleeve and abuts against an interior surface of the housing;
- and
- an end cap mounted to the housing such that the plurality of sleeve protrusions abut against the end cap, wherein the end cap comprises a second port opposite the first port of the housing.
A hydraulic system comprising:
- a cylinder having a chamber;
- and
- a flow control valve fluidly coupled to the chamber of the cylinder and configured to control fluid flow to and from the chamber, wherein the flow control valve comprises:
- a housing, wherein the housing comprises a first port fluidly coupled to the chamber of the cylinder,
- a sleeve disposed within the housing, wherein the sleeve has a first end and a second end opposite the first end, wherein the sleeve comprises a plurality of sleeve protrusions at the first end and a plurality of fluid flow channels are formed between adjacent sleeve protrusion,
- a seal carrier disposed within the sleeve, wherein the seal carrier comprises a carrier protrusion that extends from the second end of the sleeve and abuts against an interior surface of the housing, and
- an end cap mounted to the housing such that the plurality of sleeve protrusions abut against the end cap, wherein the end cap comprises a second port opposite the first port of the housing and fluidly coupled to a fluid line to receive fluid therefrom or provide fluid thereto.
A method for assembling a flow control valve, the method comprising:
- positioning a sleeve within a housing, wherein the sleeve has a first end and a second end opposite the first end, wherein the sleeve comprises a plurality of sleeve protrusions at the first end and a plurality of fluid flow channels are formed between adjacent sleeve protrusions, and wherein the housing comprises a first port;
- positioning a seal carrier within the sleeve, wherein the seal carrier comprises a carrier protrusion that extends from the second end of the sleeve and abuts against an interior surface of the housing;
- and
- mounting an end cap to the housing such that the plurality of sleeve protrusions abut against the end cap, wherein the end cap comprises a second port opposite the first port of the housing.
