Stem arrangement for pivot actuated sleeve valve
First Claim
1. A valve assembly comprising:
- a valve body;
a fluid passage through the valve body having an inlet end and an outlet end;
a valve seat defined within the fluid passage;
a sleeve axially slidable within the fluid passage and having an upstream end, a downstream end, and an axial flow passage in communication with the inlet end and the outlet end of the fluid passage; and
a valve stem pivotally mounted at a stem pivot spaced radially from the fluid passage, the valve stem being actuable to slide the sleeve between an open position with the downstream end spaced from the valve seat and a closed position with the downstream end borne against the valve seat to selectively control fluid flow through the flow passage to the outlet end, wherein one end of the valve stem is coupled to the sleeve at a joint and wherein the stem pivot accommodates relative axial movement of the valve stem as the sleeve slides within the fluid passage.

Abstract
A valve assembly has a valve body and a fluid passage through the valve body with an inlet end and an outlet end. A valve seat is defined within the fluid passage. A sleeve is axially slidable within the fluid passage and has an upstream end, a downstream end, and an axial flow passage in communication with the inlet end and the outlet end of the fluid passage. A valve stem is pivotally mounted at a stem pivot spaced radially from the fluid passage. The valve stem is actuable to slide the sleeve between an open position with the downstream end spaced from the valve seat and a closed position with the downstream end borne against the valve seat to selectively control fluid flow through the flow passage to the outlet end. One end of the valve stem is coupled to the sleeve at a joint. The stem pivot accommodates relative axial movement of the valve stem as the sleeve slides within the fluid passage.

7. A sleeve valve assembly comprising:
-
a valve body defining a fluid passage within an inlet end and an outlet end;
a valve seat within the fluid passage;
a stem housing extending radially from the valve body;
a sleeve axially slidable within the fluid passage and having an axial flow passage in communication with the inlet end and the outlet end of the fluid passage; and
a valve stem partly extending through the stem housing and being pivotable about a stein pivot to slide the sleeve between an open position and a closed position to selectively control fluid flow through the valve passage to the outlet end, wherein one end of the valve stem is coupled to the sleeve at a joint and wherein the stem pivot accommodates relative movement of the valve stem in an axial direction of the valve stem as the sleeve slides within the fluid passage. - View Dependent Claims (8, 9, 10, 11, 12)

13. A sleeve valve assembly comprising:
-
a valve body defining a fluid passage with an inlet end and an outlet end;
a valve seat within the fluid passage;
a sleeve axially slidable within the fluid passage and having an upstream end, a downstream end, and an axial flow passage in communication with the inlet end and the outlet end of the fluid passage; and
a valve stem pivotally mounted at a stem pivot spaced radially from the fluid passage, the valve stem extending generally radially from the sleeve and being actuable to slide the sleeve between an open position with the downstream end spaced from the valve seat and a closed position with the downstream end borne against the valve seat, wherein one end of the valve stem is pivotally coupled to the sleeve at a joint at a fixed location on the sleeve, and wherein the stem moves axially relative to a valve stem axis as the sleeve slides within the fluid passage.
