The pressure of compressed air supplied to an object to be filled with air is controlled at a specified pressure or less without using a relief valve. Given that a cylinder volume (stroke volume) during a piston moves from the lower dead point to the top dead point is V, a cylinder volume (compression volume) when the piston reaches the top dead point is V, the atmospheric pressure is P, and the specified pressure is P, the compression volume Vin the compressor system satisfies the following expression (1). The diameter D of the air intake hole of an air intake valve provided on the piston is 3 to 15 mm.0.8&#xd7;{1&#xd7;/()}=&#x3c;2&#x3c;1.0&#xd7;{1&#xd7;/()}&#x2003;&#x2003;(1)

Compressor system, and puncture repair kit using same

In the present invention, a difference between a pressure displayed by a manometer of a compressor device and an actual internal pressure of a tire can be reduced. A compressor device () and a bottle unit () are directly connected. A cap () attached to the bottle unit () comprises a unidirectional valve () for preventing a reverse flow of a flat tire sealing agent to the side of the compressor device. A cylinder () of the compressor device () is provided with a pump chamber (), and a surge chamber () which receives the compressed air from the pump chamber through an exhaust valve (), wherein a volume (Q) of the surge chamber () is 1.0 to 3.0 times of the stroke volume of a piston () in the pump chamber ().

Sealant bottle for tire repair kit

Tire repair kit

A device and a method for making a tire puncture sealant having a higher concentration of propylene glycol are disclosed, wherein the device comprises: a container having a cylindrical space for a mixed solution of rubber latex and a tackifier; a squirter comprising at least one spout for pouring propylene glycol on the surface of the mixed solution in the container at a rate of 0.01 to 1.0 liter/minute per spout; and an agitator for the mixed solution in the container, comprising a stirring blade rotatable in the mixed solution to cause said surface a current speed of the mixed solution in a range between about 1.0 and about 10.0 meter/second during pouring the propylene glycol.

Tire puncture sealant and method for making

A puncture sealant supplying/removing apparatus includes a pressure-resistant bottle, an apparatus body on which the pressure-resistant bottle can be mounted, supply hose means which supplies or returns a puncture sealant accommodated in the pressure-resistant bottle to or from a tire, and a high pressure air source. The apparatus body comprises a venturi flow-path having a venturi portion, a first flow-path extending from the venturi portion into the pressure-resistant bottle, and a second flow-path extending from an inside of the pressure-resistant bottle and connected to one end of the supply hose means. The venturi flow-path is provided at its one end with an air intake which is connected to the high pressure air source, the venturi flow-path is provided at its other end with an opening/closing tool capable of opening and closing the other end.

Supplying/removing apparatus of puncture sealant of tire

Tire puncture sealant set

This invention relates to high-speed radial tires, and more particularly to radial tires wherein the thickness ratio (Gc-Gs)/Gc, that is the ratio of the difference between the crown tread thickness Gc, which is a thickness of the tread on the equator of the tire, and the shoulder tread thickness Gs, which is a thickness of the tread of the ground contact surface at the outer edge in direction of the tire axis, to the crown tread thickness Gc is set to be 0 or more and 0.8 or less. By setting the ratio within a range of 0 to 0.8, the force Fs acting in the radial direction on the tread shoulder part, out of the total load acting to the tire, is decreased, thus, the deformation in the bead part is diminished and the permanence in the bead part can be improved. In a tire having the ratio of 0 to 0.8, by setting the angle of the belt cords to be 0 to 20 degrees, it can be used for aircraft and by setting the angle of the belt cords to be 20 to 40 degrees and the aspect ratio to be 60% or less, it can be used for high-speed passenger cars.
