摘要： A radiator cap composed of a cap body, a compression gasket assembly connected to the cap body and adapted to open and close in accordance with the pressure of the coolant in the radiator, a float engaged with the cap body so as to move up and down in accordance with the level of the coolant. The upper edge of the float is formed so that upon contact with a gasket assembly, a valve is formed with said gasket assembly. A reed switch secured to the cap body is opened or closed in response to movement of the float so that the reed switch actuates suitable warning means when the level of coolant falls over a predetermined line.

摘要： PURPOSE:In an engine cooling system having in front of a radiator a fan shrouding and an electric fan, to reduce noise from a stay formed in concave section using a sheet of a specific thickness. CONSTITUTION:The intake duct part 3c of a fan shrouding 3 is formed in a bell- mouthed shape along the entire circle. The end portion 5a of a stay 5 is formed in U-shape to catch around the rim of the intake duct part 3c. The stay 5 and the fan shrouding 3 are joined together by fitting the rim of the intake duct part 3c into the forcibly expanded U-shaped portion 5a of the stay 5. Then, the stay 5 and the fan shrouding 3 are fastened together by spot-welding the end portion 5b of the stay 5 to the cylindrical part 3a of the fan shrouding 3. The section of the stay 5 is formed in U-shape opening against the air stream and the width (1) of the opening end of the section is determined over two times under eight times of the thickness (t) of the sheet.

摘要： PURPOSE:To positively detect the shortage of water in a radiator, by incorporating a float system switch for detecting the water-level of cooling water to a cap for the radiator. CONSTITUTION:A water injecting port 2 with a cap 8 is connected to an upper tank 3 of a radiator communicated with the radiator of an internal combustion engine not shown in the figure through conduits 4. A reserve tank not shown in the figure is communicated in the water injecting port 2 while a pressurizing valve 13 for opening a communicating hole 15 when pressure in the tank 3 becomes not less than fixed value is disposed to a communicating portion with the upper tank 3. A float 16 that is arranged by means of a cylindrical holding material 11a while a permanent magnet 18 is fixed to its internal upper portion is disposed between the pressurizing valve 13 and the cap 8 in a sliding-free shape. A reed switch 19 is arranged to the cap 8 at locations where the switch faces to the magnet 18, and an alarm is given by means of the switch 19 when the float 16 lowers not more than fixed value.

摘要： A radiator cap sit on 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 locates lower side than the connecting point between a sealing portion of the pressure valve and the filler neck, the rotating moment which returns the pressure valve horizontally is generated when the pressure valve is inclined. So that the pressure valve is well prevented to incline. The pressure valve of the present invention can maintain its position horizontally and can open the filler neck always at the predetermined pressure.
