- the outlet section 26 of the pump 12 , the valve unit 30 and the pipe 29 constitute a tire pressure holding system in accordance with the present invention.
- the valve unit 30 includes a shaft-like stem 32 extending through a through hole 14 A formed in the reel 14 .
- a tire tube 13 C provided inside the tire 13 is fixed to a proximal end of the stem 32 , whereupon a space 32 A axially defined inside the stem 32 communicates with an inner space 13 A of the tire 13 or more specifically, with an inner space of the tire tube 13 C.
- the stem 32 includes a base stem 33 fixed to the tire tube 13 C and an extended stem 34 engaged with an outer face of the base stem 33 .
- An annular disc 35 is also engaged with the outer face of the base stem 33 .
- An edge of the through hole 14 A is held between the extended stem 34 and the disc 35 , whereupon the stem 32 is fixed so as to stand from the reel 14 toward the pump 12 .
- the stem 32 further includes a valve core 40 and a release valve 65 disposed in turn in this order from the tire 13 side.
- the valve core 40 includes a flange-like rubber plug 62 fixed to one end of a shaft 61 extending through a cylindrical member 60 as shown in FIG. 5.
- the rubber plug 62 serves as a check valve lid in the present invention.
- the release valve 66 has such an elongated shape as to be direct moved in the extended stem 34 and includes a flange 67 on an end at the side thereof spaced away from the valve core 40 , as shown in FIG. 3.
- a surrounding wall 68 projects from an outer edge of the flange 67 toward the valve core 40 .
- a disc-shaped sealing member 69 is provided inside the surrounding wall 68 .
- the extended stem 34 has a stepped portion 34 D formed on an inner face thereof.
- a circular projecting member 70 projects from an inner edge of the stepped portion 34 D toward a direction in which the projecting member is departed from the valve core 40 .
- a coil spring 71 is disposed, in a compression-deformed state, between the flange 67 of the release valve 66 and a distal end wall 34 S of the extended stem 34 .
- the sealing member 69 of the release valve 66 is pressed against the circular projecting member 70 by the spring force of the coil spring 71 .
- the space 32 A in the stem 32 includes a release chamber 32 C separated from the valve core 40 as the result of close adherence of the sealing member 69 of the release valve 65 and the circular projecting member 70 .
- the release chamber 32 C includes a release hole 73 formed through a side wall of the extended stem 34 near the projecting member 70 .
- the space 32 A further includes a charge chamber 32 B defined by the valve core 40 and a closely adhered portion between the sealing member 69 of the release valve 65 and the circular projecting member 70 .
- the charge chamber 32 B includes an air supply hole 72 formed through a side wall of the extended stem 34 .
- a pipe 29 extending from the pump 12 has an end connected to the air supply hole 72 .
- the outlet section 26 of the pump 12 , the stem 32 and the pipe 29 constitute a conduit 74 in the invention, as shown in FIG. 2.
- the release valve 65 has an end against which the shaft 61 of the valve core 60 is pressed.
- the release valve 65 and the shaft 61 are urged by the aforesaid coil springs 63 and 71 so that the valve and the shaft are pressed in opposite directions respectively. Accordingly, the release valve 65 and the shaft 61 are substantially connected to each other, whereupon the valve core 40 is operated in synchronization with release valve 65 .
- the pump 12 is inoperative when the bicycle 10 is stopped.
- the valve core 40 is closed and the release valve 65 is open in the valve unit 30 .
- the pump 12 is driven in synchronization with revolution of the wheel 11 . Consequently, compressed air is supplied into the charge chamber 32 B of the valve unit 30 . Part of the compressed air flows through the release valve 65 , leaking from the release hole 73 .
- an amount of compressed air supplied from the pump 12 becomes larger than an amount of compressed air leaking from the release hole 73 , whereupon the internal pressure of the charge chamber 32 B is increased.
- the valve core 40 is opened on the basis of a difference between the internal pressures of the charge chamber 32 B and the tire 13 .
- the release valve 65 is then closed in synchronization with the opening of the valve core 40 , whereby the compressed air from the pump 12 is supplied into the tire 13 .
- the valve core 40 is closed and the release valve 65 is opened in synchronization with the closure of the valve core, whereupon the compressed air from the pump 12 is released outside the valve unit 30 .
- compressed air can automatically be supplied into the tire 13 and accordingly, the internal pressure of the tire can be stabilized. Furthermore, the valve core 40 and the release valve 65 are linked with each other so that the release valve is held open while the valve core is closed. Accordingly, since an excessive amount of compressed air from the pump 12 is smoothly released outside, a revolution resistance of the wheel 11 can be reduced. Additionally, the tire pressure holding system 31 of the embodiment is divided into the pump 12 , the valve unit 30 and the pipe 29 connecting the pump and the valve unit. Consequently, the length of the pipe 29 can be changed so as to correspond to various sizes of wheels 11 , and the pump 12 and the valve unit 30 can be used as common components for the various sizes of wheels 11 .
- FIGS. 7 and 8 illustrate a second embodiment of the invention.
- the valve unit 30 V of the second embodiment differs from the valve unit of the first embodiment in the construction of the release valve 65 V.
- the release valve 65 provided in the valve unit 30 V of the second embodiment has a smaller axial length than the release valve 65 in the first embodiment, so as not to be brought into contact with the shaft 61 of the valve core 40 .
- the sealing member 69 V is made of a rubber tube with a circular section into such an annular shape that the sealing member is fitted in the inside of the surrounding wall 68 .
- the other construction of the valve unit 30 V is the same as that of the valve unit 30 in the first embodiment.
- both of the valve core 40 and the release valve 65 are closed when the pump 12 is inoperative due to stop of the bicycle 10 , as shown in FIG. 7.
- the pump 12 is driven so that the charge chamber 32 B is charged with compressed air.
- the valve core 40 is opened due to the difference between the internal pressures of the charge chamber 32 B and the tire 13 to supply compressed air into the tire 13 .
- the valve core 40 is closed when the internal pressure of the tire 13 is increased to the normal internal pressure.
- the release valve 65 is opened to release an excessive amount of compressed air outside the valve unit 30 V. See FIG. 8.

- the intermediate valve 80 is adapted to be direct moved in the passage 74 as described above and urged by a coil spring 84 toward the valve core 40 side.
- the extended stem 34 has a release hole 73 formed in a distal end wall 34 S thereof.
- valve unit 30 W of the third embodiment when air leaks at the valve core 40 side, pressure is increased at the valve core 40 side of the sealing member 82 of the intermediate valve 80 .
- the intermediate valve 80 is moved to the side away from the valve core 40 against a spring force of the coil spring 84 , and the sealing member 82 is deformed in the direction opposite the direction of its curvature thereby to be spread outward. Consequently, the outer edge of the sealing member 82 is closely adhered to the inner circumferential face of the stem 32 , thereby preventing air in the tire 13 from leaking outside through the intermediate valve 80 .
- valve core 40 and the intermediate valve 80 limit leakage of air from the tire 13 in association.

- valve unit 30 Y According to the above-described valve unit 30 Y, the same effect can be achieved from the fifth embodiment as from the first to third embodiments. Furthermore, when an external pump is connected to the pump mount 100 , air can be supplied into the tire 13 by the external pump as occasion demands.
- FIG. 12 illustrates a sixth embodiment of the invention.
- the sixth embodiment is also a modified form of the fourth embodiment.
- the release valve 65 V of the valve unit 30 X of the fourth embodiment is provided integrally with the outlet section 26 of the pump 12 . More specifically, the cylindrical wall 27 of the outlet section 26 has an outlet 27 A and a cave hole 27 B in which the release valve 65 V is disposed.
- the release valve 65 V When the release valve 65 V is fixed to the pump 12 as described above, the release valve 65 V can be disposed at the revolution center side of the wheel. Consequently, inertia (moment of inertia) due to the release valve 65 V can be reduced as compared with a case where the release valve is provided on an outer edge of the wheel.
- FIGS. 13 to 15 illustrate a seventh embodiment of the invention.
- the seventh embodiment differs from the first embodiment in the construction of the pump.
- the pump 12 V used in the seventh embodiment employs a slider crank mechanism 20 V to produce compressed air.
