Abstract
An isolation mounting system is provided for the purpose of supporting a throttle body structure which is completely supported by an elastomeric support, but is held in non-contact association with an air intake manifold in order to effectively isolate the throttle body structure from vibration. This isolation protects potentially delicate components contained within a component housing that is rigidly attached to the throttle body structure.
Claims19
A marine propulsion apparatus, comprising:
- an internal combustion engine having an air intake chamber;
- a throttle body structure having a throttle plate supported for rotation within a cavity of said throttle body structure;
- an elastomeric support member attached to said air intake chamber and to said throttle body structure to support said throttle body structure in non-contact association with said air intake chamber;
- and
- an adapter plate attached between said internal combustion engine and said elastomeric support member.

A marine propulsion apparatus, comprising:
- an internal combustion engine having an air intake chamber;
- a throttle body structure having a throttle plate supported for rotation within a cavity of said throttle body structure;
- an elastomeric support member attached to said air intake chamber and to said throttle body structure to support said throttle body structure in non-contact association with said air intake chamber;
- and
- an isolator plate attached to said throttle body structure for the purpose of captivating a portion of said elastomeric support member between said isolator plate and said throttle body structure, said elastomeric support member having a sealing lip which extends between said isolator plate and said throttle body structure for the purpose of preventing air from flowing into said air intake chamber from between said isolator plate and said throttle body structure.

A marine propulsion apparatus, comprising:
- an internal combustion engine having an air intake chamber, said internal combustion engine comprising a crank shaft which is supported for rotation about a generally vertical axis;
- a throttle body structure having a throttle plate supported for rotation within a cavity of said throttle body structure;
- an elastomeric support member attached to said air intake chamber and to said throttle body structure to support said throttle body structure in non-contact association with said air intake chamber;
- an isolator plate attached to said throttle body structure for the purpose of captivating a portion of said elastomeric support member between said isolator plate and said throttle body structure, said elastomeric support member having a sealing lip which extends between said isolator plate and said throttle body structure for the purpose of preventing air from flowing into said air intake chamber from between said isolator plate and said throttle body structure;
- and
- a motor attached to said throttle body structure, said motor being operatively attached to a shaft of said throttle plate to rotate said throttle plate within said cavity of said throttle body structure;
- and a rotational position sensor attached to said throttle body structure and operatively attached to said shaft of said throttle plate to determine a rotational position of said shaft.
