Abstract

Disclosed is a system of the type comprising an engine for performing a primary work function and at least one secondary work function, in which operation of the engine is characterized by alternating periods of primary work function load and no-load conditions, the system including means for loading the engine with the secondary work function only during the periods of primary work function no-load condition.

Claims

1. In a system of the type comprising an internal combustion engine for performing a primary work function and at least one secondary work function, in which operation of said engine is characterized by alternating periods of primary work function load and no load conditions, said internal combustion engine being of the type including pressure differential means responsive to said load and no load conditions, means for loading said engine with said secondary work function only during said periods of primary work function no load condition, said loading means comprising:

a flat flexible member having a sealed end and a hollow core communicating with said pressure differential means; and

wherein changes in pressure within said pressure differential means causes flex of said member responsive thereto.

2. The system recited in claim 1 further comprising:

an electrical power source;

charging means coupled to said power source and to said engine as one of said secondary work functions; and

wherein said charging means is operated by said engine only during said periods of primary work function no load condition.

3. The system recited in claim 2, said system defining a vehicle wherein said primary work function comprises motivating said vehicle.

4. A system as recited in claim 3 wherein said vehicle includes accessories cArried thereby and operated by said engine as said secondary work functions.

5. A system as recited in claim 4 wherein operation of said vehicle is characterized by alternating periods of acceleration and deceleration with occasional intervening periods of constant vehicle velocity, said deceleration periods substantially defining said periods of primary work function no load condition.

6. In a vehicle of the type including an internal combustion engine for motivating said vehicle such that operation of said vehicle is characterized by alternating periods of acceleration and deceleration with occasional intervening periods of constant vehicle velocity, said engine of the type having an intake manifold the pressure within which changes responsive to said periods of acceleration and deceleration, the combination comprising:

at least one accessory carried by said vehicle;

means for coupling and decoupling said accessory to said engine so as to be intermittently driven thereby, said coupling and decoupling means comprising;

a flat flexible member having a sealed end and a hollow core communicating with said manifold;

means for flexing said member responsive to pressure changes in said manifold; and

means for coupling said accessory to said engine during said periods of vehicle deceleration.

7. The combination recited in claim 6 wherein said coupling-decoupling means further comprises means for sensing the approximate deceleration point of said vehicle.

8. The combination recited in claim 6 wherein said flexing means comprises:

said flat member defining a twist in a direction axial with said hollow core; and

wherein pressure changes in said manifold causes flexing of said member in said axial direction.

9. The combination recited in claim 8 further comprising:

a second flat, flexible member having an axial twist opposite to that of said one flat, flexible member; and

a pair of juxtaposed switch contacts, each contact being carried by one of said flexible members at the respective sealed end thereof.

10. The combination recited in claim 9 further comprising means for adjusting the throw of one of said switch contacts whereby said contacts are adapted to close only upon sensing by said members of a predetermined manifold pressure.

11. The combination recited in claim 10 further comprising thermal-latching means serially coupled to one of said contacts.

12. The combination recited in claim 11, wherein said thermal latching means comprises a bi-metallic element.

13. The combination recited in claim 6, further comprising:

a current source carried by said vehicle;

said accessory comprising charging means coupled to said current source for charging said current source when coupled to said engine.
