Abstract
The present invention provides a safety cap system with a pressure and temperature activated external locking cum unlocking means for an automotive cooling system to prevent accidental removal of the safety cap. The safety cap further uses a torque overriding mechanism to ensure an effective closure and removal torque.
Claims23
A safety cap system for engine cooling devices, said system comprising:
- a. a reservoir container with a neck for storing cooling material;
- b. a removable safety cap with torque overriding means to provide and indicate correct installation and torque to a user, said cap coupled firmly to the neck of the reservoir;
- c. a flange means on the circumference of said safety cap;
- d. at least an external locking cum unlocking means, disposed on the reservoir container in close proximity with the flange, to engage or disengage the flange of the safety cap;
- and
- e. a pressure and temperature sensitive metallic sensor means housed in said locking cum unlocking means to sense variations in pressure and temperature levels of the reservoir container and to effect the locking or unlocking of the safety cap, said metallic sensor having conical and helical shapes.
The method of claim 19, wherein the plunger unit gets activated when the pressure in the reservoir container exceeds a pressure level of above 2 psi and thereby engaging the locking mechanism of the safety cap.
The safety cap system for engine cooling devices as substantially described herein with reference to specification and diagrams.
The method of providing fail-proof safety cap system for engine cooling devices as substantially described herein with reference to specification and diagrams.
