Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
136 words
An internal combustion engine, which comprises: an engine having a crankcase; a container for collecting crankcase vapors, said containers having a desiccant disposed therein, said container being positioned in heat exchange relation to said engine; and means for providing fluid communication alternately between (1) a first position coupling said container to at least a part of said crankcase of said engine when said engine is not operating in order to supply a crankcase vapors to the container and (2) a second position coupling said container to ambient when said engine is operating, said desiccant absorbing crankcase vapors when said engine is not running and releasing the crankcase vapors previously absorbed to the atmosphere when said engine is not running whereby in order that crankcase vapors contained therein are released by the heated desiccant to the atmosphere.
Claim 2
Dependent Claim
136 words
An internal combustion engine, which comprises: an engine having a crankcase; a container for collecting crankcase vapors, said containers having a desiccant disposed therein, said container being positioned in heat exchange relation to said engine; and means for providing fluid communication alternately between (1) a first position coupling said container to at least a part of said crankcase of said engine when said engine is not operating in order to supply a crankcase vapors to the container and (2) a second position coupling said container to ambient when said engine is operating, said desiccant absorbing crankcase vapors when said engine is not running and releasing the crankcase vapors previously absorbed to the atmosphere when said engine is not running whereby in order that crankcase vapors contained therein are released by the heated desiccant to the atmosphere.
Claim 3
Dependent Claim
49 words
The apparatus as described in claim 1, wherein: said hollow interior portions of said engine include a crankcase wherein said crankcase has an upper and a lower part and said means for providing fluid communication couples said container to said upper part of said crankcase in said first position.
Claim 4
Dependent Claim
30 words
The apparatus as described in claim 1, wherein: said apparatus includes means for regenerating said desiccant, said means for regenerating including positioning said container proximate to a source of heat.
Claim 5
Dependent Claim
18 words
The apparatus as described in claim 3, wherein: said source of heat is said exhaust manifold of engine.
Claim 6
Dependent Claim
19 words
The apparatus as described in claim 4, wherein: said means for providing fluid communication includes at least one valve.
Claim 7
Dependent Claim
27 words
The apparatus as described in claim 1, wherein: said valve operates to substantially concurrently open to ambient and interrupt fluid communication between said container and said crankcase.
Claim 8
Dependent Claim
14 words
The apparatus as described in claim 6, wherein: said valve is a three-way valve.
Claim 9
Dependent Claim
15 words
The apparatus as described in claim 5, wherein: said valve is a solenoid operated valve.
Claim 10
Dependent Claim
15 words
The apparatus as described in claim 8, wherein: said valve is a diaphragm operated valve.
Claim 11
Dependent Claim
74 words
The apparatus as described in claim 1, further including: an elastic fluid impervious chamber and means for sealing said elastic fluid impervious chamber with the interior thereof in fluid communication with the inside of said hollow interior portions of said engine; and a housing disposed in spaced relationship around said elastic fluid impervious chamber with at least portions of the space intermediate said housing and said elastic fluid impervious chamber being vented to ambient.
Claim 12
Dependent Claim
13 words
The apparatus as described in claim 1, further including: a pressure release means.
Claim 13
Dependent Claim
12 words
The apparatus as described in claim 1, further including: vacuum release means.
