Abstract
An assembly includes a valve housing and a valve element such as a poppet valve. The valve housing includes a tubular duct and an annular valve seat disposed within the tubular duct. A first flowpath includes an inner bore of the annular valve seat. A second flowpath includes an aperture formed between the annular valve seat and the tubular duct. The poppet valve is configured to engage the annular valve seat and substantially close the first flowpath when the poppet valve is in a first position. The poppet valve is further configured to disengage the annular valve seat and at least partially open the first flowpath when the poppet valve is in a second position.
Claims19
An assembly, comprising:
- a valve housing including a tubular duct and an annular valve seat disposed within the tubular duct, wherein a first flowpath comprises an inner bore of the annular valve seat, a second flowpath comprises an aperture formed between the annular valve seat and the tubular duct, and the aperture extends circumferentially about a centerline of the inner bore;
- and
- a poppet valve configured to engage the annular valve seat and close the first flowpath when the poppet valve is in a first position, the poppet valve configured to disengage the annular valve seat and at least partially open the first flowpath when the poppet valve is in a second position, and the poppet valve comprising a head and a stem;
- the stem projecting out from the head, through a second aperture in the tubular duct, and out of the valve housing.
An assembly, comprising:
- a valve housing including an inlet and an outlet, and configured with an inner flowpath and an outer flowpath that extends at least one-hundred and eighty degrees around the inner flowpath, wherein the inner flowpath and the outer flowpath are fluidly coupled, in parallel, between the inlet and the outlet;
- and
- a valve element configured to close the inner flowpath when the valve element is in a first position, and the valve element configured to at least partially open the inner flowpath when the valve element is in a second position;
- and
- an actuator configured to move the valve element between the first position and the second position, the actuator configured as one of an electrically controlled actuator, a pneumatically controlled actuator or a hydraulically controlled actuator;
- wherein the outer flowpath is open when the valve element is in the first position and the second position.
