Abstract
The manifold cross-over control valve includes a powdered metal mounting base (10) which is mounted in a bore in a cross-over passage of an intake manifold (B). A frame (40) which extends into the cross-over passage from the mounting base seals against passage around its periphery and defines an exhaust gas aperture (42) therethrough. A pin (70) mechanically fastens the frame to the mounting base. A butterfly plate (80) is mounted on rotatable shaft (90) adjacent the frame for selectively opening and closing the exhaust gas aperture. The pin engages the butterfly plate in its fully open position to limit its rotational movement. A pneumatic actuator (D) is mounted by a bracket (30) to the mounting base for selectively rotating the shaft to control the passage of exhaust gases through the cross-over control valve.
Claims18
A control valve comprising:
- a mounting base;
- a peripheral frame defining an aperture therethrough and extending transverse to the mounting base;
- a bottom plate connected with the frame opposite the mounting base and extending substantially parallel to the mounting base;
- a valving member disposed adjacent the peripheral frame for selectively opening and closing the frame aperture;
- a mechanical fastening means for mechanically fastening the frame with the mounting base, the mechanical fastening means further being operatively connected with the bottom plate, whereby the bottom plate is connected with the mounting base by both the frame and the mechanical fastening means.
A control valve comprising:
- a mounting base;
- a frame which defines an aperture;
- a shaft rotatably mounted through the mounting base;
- a plate operatively connected with the shaft for rotation therewith, the plate being disposed adjacent the frame for rotation between a first position in which the aperture is blocked and a second position in which the aperture is at least partially unobstructed;
- and,
- a pin for fastening the frame and mounting base together, the pin extending adjacent the plate to limit the rotational movement thereof.
An automotive cross-over control valve comprising:
- a powdered metal mounting base which is adapted to be mounted in an intake manifold cross-over passage;
- a frame having a periphery generally in conformity with a transverse cross section of the intake manifold cross-over passage and including a first frame portion disposed adjacent the mounting base, a second frame portion, and frame leg portions connecting the first and second frame portions such that an exhaust gas aperture through the frame is defined thereby;
- a bottom plate operatively connected with the second frame portion;
- a shaft rotatably mounted in the mounting base and bottom plate;
- a butterfly plate mounted on the shaft for rotation therewith between a first position abutting the frame leg portions to close the exhaust gas aperture and a second position displaced from the frame leg portions to open the exhaust gas aperture;
- a mechanical fastener for mechanically fastening the first frame portion and the mounting base, the mechanical fastener engaging the butterfly plate in the second position to limit rotational movement thereof;
- and,
- actuating means operatively connected with the shaft for selectively rotating the butterfly plate between the first and second positions.
