Abstract
This document discusses, among other things, a valve assembly for controlling an exhaust pressure of a gas combustion system. The valve assembly can include a valve housing, a flapper, and a biasing device. The valve housing can be coupleable to an exhaust pipe. The flapper can be pivotably couplable to the valve housing to pivot between a full open position and a restricted position in response to exhaust pressure. The biasing device can be couplable to the housing and extendable into the exhaust pipe to engage the flapper, where the biasing device can be configured to bias the flapper toward the restricted position and can be configured to resist movement of the flapper between the restricted position and the full open position.
Claims16
A valve assembly for controlling an exhaust pressure of a gas combustion system, the valve assembly comprising:
- a valve housing connected to an exhaust pipe;
- a flapper pivotably connected to the valve housing to pivot between a full open position and a restricted position in response to exhaust pressure;
- and
- a biasing device including;
- a plunger located within the valve housing and engaged with the flapper;
- a damper receiver including a plurality of slots extending through the damper receiver;
- and
- a damper secured to the damper receiver and connected to the plunger, the damper configured to contact the damper receiver and the plunger to bias the flapper toward the restricted position and to resist movement of the flapper from the restricted position to the full open position.
A valve assembly for controlling an exhaust pressure of a gas combustion system, the valve assembly comprising:
- an exhaust pipe including a hinge port;
- a valve housing connected to the exhaust pipe;
- a flapper located at least partially within the exhaust pipe, the flapper including a knuckle extending through the hinge port to pivotably connect the flapper to the valve housing, the flapper configured to pivot between a full open position and a restricted position in response to exhaust pressure;
- and
- a biasing device comprising:
- a plunger located within the valve housing and engaged with the flapper;
- a damper receiver connected to the valve housing;
- and
- a damper located at least partially within the damper receiver, the damper engaged with the plunger to bias the flapper toward the restricted position and to resist movement of the flapper from the restricted position to the full open position.
An internal combustion engine comprising:
- a gas combustion system;
- an exhaust pipe;
- and
- a valve assembly for controlling an inlet pressure to a turbine of the gas combustion system,
- the valve assembly comprising:
- a valve housing coupled to the exhaust pipe;
- a flapper pivotably coupled to the valve housing to pivot between a full open position and a restricted position in response to exhaust pressure;
- an actuator coupled to the housing and extending into the exhaust pipe to engage the flapper;
- and
- a pressure sensor coupled to one of the exhaust pipe to sense an actual exhaust pressure within the exhaust pipe;
- and
- a controller configured to:
- operate the biasing device to actuate the flapper by the actuator between the full open position and the restricted position based on the actual pressure having been sensed.
