Improved cap for closing the filling pipe of a radiator or like liquid container

An over-pessure and under-pressure valve closure cap for a radiator comprises a plastics cover 1 having a peripheral flange 1a from which locking fingers 10, 11 extend inwardly, the lower face of the cover having a surface resting on the upper rim of a radiator filling tube 2 and an annular resilient lip 34 engaging the interior of the tube, a boss 20 supporting a double valve 23 forced against a button 21 by a spring 27. Diametrically opposed finger tabs 4, 5 are formed integrally with the cover 1 which is preferably a moulded superpolyamide. Notches 13, and stops are located on the edge 12 of the filling tube 2 for engagement with the locking fingers 10, 11 so that the cover 1 may be secured in position. The valve 23 has a radially extending slot which enables the valve to be assembled over the button 21. An edge 30a of a synthetic rubber lining 30 fits into-an annular groove 29 in the valve 23 which may also be made of superpolyamide. If an under-pressure exists in the radiator, the lining 30 is deflected downwards and a boss portion 31 of the lining no longer seals a hole 32 which connects with the radiator through holes 33. An over-pressure in the radiator causes the lining 30 to be lifted from its seat 2a on the filling tube 2 and the pressure is vented through an overflow pipe 36. A rounded portion 34a of the lip 34 remains in contact with the wall of the filling tube 2 when the cover 1 is removed until the lining 30 has been withrawn from the seat 2a, thereby ensuring that any fluid under pressure in the radiator is vented through the overflow pipe 36 and not up the filling tube towards the faces of the operator.

Closing cap for motor vehicle radiator

The invention relates to a closing cap (10) for the fixed tubing of a motor vehicle radiator, comprising an inner part (14) with a flow connection means between the inside and the outside of the container, as well as a distributing mechanism for freeing and closing the flow connection means. A valve body (22) of the distributing mechanism (11), which can be reciprocated, is compressed under pre-stress towards the inside of the container against a sealing seat (21) at the inner part (14) of the cap, so that said valve body can be lifted from said sealing seat (21) when a threshold value of the pressure inside the container is exceeded. In order to produce a closing cap (10) which does not open in case of overpressure resulting from heat accumulation and which ensures that the container is protected in case of a continuing increase of pressure, in a simple and cost-effective way, the invention provides for in-use controlled adjustment of the pre-stress used for compressing the valve body (22) against the sealing seat (21).

Automotive radiator cap

ABSTRACT A radiator cap for a filler neck of an automotive radiator tank. The radiator cap has an inner cap rotatably connected with an outer cap, a pressure valve functionally connected with the inner cap in such a manner that the pressure valve can move vertically so that the pressure valve opens the filler neck when the pressure within the radiator tank increases up to a predetermined pressure. The radiator cap further includes a coil spring provided between the inner cap and the pressure valve for biasing the pressure valve toward the filler neck. Since the connecting point between the coil spring and the pressure valve is lower than the connecting point between a sealing portion of the pressure valve and the filler neck, a rotating moment is generated which returns the pressure valve to a horizontal position whenever the pressure valve becomes inclined, and prevents any tendency to return to an inclined position. The pressure valve disclosed can maintain its position horizontally and can open the filler neck always at the predetermined pressure.
