摘要:
A safety cap device for controlling a pressure in a radiator includes a valve seat provided with a valve receiving space in which a first communicating hole is formed. A negative pressure valve is provided movably in the first communicating hole. A seal is disposed on a receiving surface of the valve seat and disposed movably with the negative pressure valve. The seal has a second communicating hole formed at a central portion thereof. A positive pressure valve is disposed on the seal and has a third communicating hole formed at a central portion thereof. A cap covers an upper portion of the valve seat. A spring is interposed between the positive pressure valve and the cap. A fluid receiving part is in the valve seat to prevent cavitation caused when an internal fluid expands.

A coolant tank for receiving a fluid from the cooling system of an internal combustion engine includes a pressurized tank having a pressurized reservoir configured to contain the fluid and an overflow tank integrated with the pressurized tank. The pressurized reservoir includes an inlet port configured to receive the fluid from the cooling system, an outlet port configured to direct the fluid from the pressurized reservoir to the cooling system, a fill neck in fluid communication with the pressurized reservoir, and a pressure cap removably coupled to the fill neck. The overflow tank includes an overflow reservoir maintained at atmospheric pressure and configured to receive overflow fluid from the pressurized reservoir when the liquid of the cooling system expands. At least a portion of the fill neck is positioned within the overflow reservoir.

A safety radiator cap has a centrally located pressure plunger that forces pins outward against the inside of a radiator fill tube to prevent opening of the cap when the system is under pressure. As the liquid cools, the pressure is reduced and the pins retract due to biasing springs which allow the cap to be removed thus ensuring that the cap can only be removed when safe. Pressure pads at the end of the pins allow an embodiment of the invention to be used in any vehicle without retrofitting.

The circuit includes an internal volume for receiving a cooling fluid, a stopper for selectively closing an opening giving access to the internal volume, and ensuring element that the cooling fluid can be discharged via a discharge outlet. The respective discharge and access openings to the internal volume are distinct from each other, and a flap valve, which is detachably fixed in relation to the stopper and which is moveable between respective closure and release positions of the access opening when the flap valve is disconnected from the stopper, is also provided. The flap valve exclusively moves from its closed position when the pressure prevailing inside the internal volume is lower than a predefined pressure value.

The invention relates to a sealing cap (11), for openings and containers. The valve arrangement (15) comprises an axiallly displaceable valve body (17), which is held in the direction of the container interior by means of a spring (22) against a first sealing seat (34), on the cap interior. The valve arrangement (15) comprises one single valve body (17), provided with a first axially effective sealing surface arrangement (20) and a second radially effective sealing surface arrangement (21). The axially effective sealing surface arrangement (20) co-ordinates with an axial seal seat (34), surrounding a defined opening (32), connecting to the container interior on the cap inner part (14). The radially effective sealing surface arrangement (21) co-ordinates with a first radial counter sealing surface (61, 62), comprising a bypass (39), for the first flow connection and a second radial counter sealing surface (61), comprising a safety relief opening (69), for the second flow connection.

A pressure cap (111) for openings in tanks, in particular in automobile radiators, has an outer cap component (110) which is provided with a locking element (113) that can be connected to the tank's neck, and provided with a handling element (112) rotatably mounted in relation to said locking element, and furthermore provided with a coupling insert (180) which is anti-rotationally mounted in the handling element (112) and which can be axially engaged in and disengaged from the locking element (113) to allow a releasably non-rotational connection between the locking element and the handling element, and which furthermore is provided with a valve assembly (115) containing a valve body (117) that can be axially moved back and forth, for releasing and blocking flow connections between the inside and the outside of the tank depending on the pressure prevailing inside the tank. To create an anti-rotation means directly governed by and in time and sequence with the conditions prevailing inside the tank, it is provided that the engaging and disengaging movement of the coupling insert (180) is derived from the pressure-dependent axial movement of the valve body (117) of the valve assembly (115).
