Abstract
Abstract A bypass passage interconnects intake manifold passages and has a bypass valve disposed therein for shifting the tuning point for inertia supercharging, the bypass valve being actuatable to close and open the bypass passage by a bypass valve actuator operatively connected between the bypass valve and an accelerator-responsive lever for closing the bypass valve when the engine load increases.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
101 words
An internal combustion engine comprising: a pair of intake manifolds having intake passages, respectively; a bypass passage interconnecting said intake passages and having a bypass valve disposed therein for shifting the turning point for inertia supercharging; an accelerator-responsive lever; a bypass valve actuator operatively connected between said bypass valve and said accelerator-responsive lever for closing said bypass valve when the engine load increases; said bypass valve actuator comprising a link operatively connected at one end to said accelerator-responsive lever and a lever connected to said bypass valve, said link having an opposite end connected to said lever through a lost-motion connection.
Claim 2
Dependent Claim
101 words
An internal combustion engine comprising: a pair of intake manifolds having intake passages, respectively; a bypass passage interconnecting said intake passages and having a bypass valve disposed therein for shifting the turning point for inertia supercharging; an accelerator-responsive lever; a bypass valve actuator operatively connected between said bypass valve and said accelerator-responsive lever for closing said bypass valve when the engine load increases; said bypass valve actuator comprising a link operatively connected at one end to said accelerator-responsive lever and a lever connected to said bypass valve, said link having an opposite end connected to said lever through a lost-motion connection.
Claim 3
Dependent Claim
23 words
An internal combustion engine according to claim 1, wherein said lost-motion connection comprises a spring acting between said link and said bypass valve.
Claim 4
Dependent Claim
144 words
An internal combustion engine comprising: a pair of intake manifolds having intake passages, respectively; a bypass passage interconnecting said intake passages and having a bypass valve disposed therein for shifting the turning point for inertia supercharging; an accelerator-responsive lever; a bypass valve actuator operatively connected between said bypass valve and said accelerator-responsive lever for closing said bypass valve when the engine load increases; said bypass valve actuator comprising a link operatively connected at one end to said accelerator-responsive lever, a lever connected to said bypass valve and having a slot, and a guide plate having a guide slot, said link having an opposite end received in and displaceable along said slots, said guide slot including an inclined portion to provide a lost-motion connection between said bypass valve and said accelerator-responsive lever to allow the latter to move after said bypass valve has been closed.
Claim 5
Dependent Claim
144 words
An internal combustion engine comprising: a pair of intake manifolds having intake passages, respectively; a bypass passage interconnecting said intake passages and having a bypass valve disposed therein for shifting the turning point for inertia supercharging; an accelerator-responsive lever; a bypass valve actuator operatively connected between said bypass valve and said accelerator-responsive lever for closing said bypass valve when the engine load increases; said bypass valve actuator comprising a link operatively connected at one end to said accelerator-responsive lever, a lever connected to said bypass valve and having a slot, and a guide plate having a guide slot, said link having an opposite end received in and displaceable along said slots, said guide slot including an inclined portion to provide a lost-motion connection between said bypass valve and said accelerator-responsive lever to allow the latter to move after said bypass valve has been closed.
Claim 6
Dependent Claim
180 words
An internal combustion engine comprising: a pair of intake manifolds having intake passages, respectively; a bypass passage interconnecting said intake passages and having a bypass valve disposed therein for shifting the tuning point for inertia supercharging; an accelerator-responsive lever; a bypass valve actuator operatively connected between said bypass valve and said accelerator-responsive lever for closing said bypass valve when the engine load increases; said bypass valve actuator comprising a link operatively connected to said accelerator-responsive lever, a first lever connected to said bypass valve and having a pin, a spring normally urging said first lever in a direction to close said bypass valve, a second lever having a slot receiving said pin, and a third lever operatively connected between said link and said second lever, said link and first through third levers being actuatable by said accelerator-responsive lever to allow said bypass valve to be closed under the force of said spring, said slot serving as a lost-motion connection between said bypass valve and said accelerator-responsive lever to allow the latter to move after said bypass valve has been closed.
Claim 7
Dependent Claim
180 words
An internal combustion engine comprising: a pair of intake manifolds having intake passages, respectively; a bypass passage interconnecting said intake passages and having a bypass valve disposed therein for shifting the tuning point for inertia supercharging; an accelerator-responsive lever; a bypass valve actuator operatively connected between said bypass valve and said accelerator-responsive lever for closing said bypass valve when the engine load increases; said bypass valve actuator comprising a link operatively connected to said accelerator-responsive lever, a first lever connected to said bypass valve and having a pin, a spring normally urging said first lever in a direction to close said bypass valve, a second lever having a slot receiving said pin, and a third lever operatively connected between said link and said second lever, said link and first through third levers being actuatable by said accelerator-responsive lever to allow said bypass valve to be closed under the force of said spring, said slot serving as a lost-motion connection between said bypass valve and said accelerator-responsive lever to allow the latter to move after said bypass valve has been closed.
