Abstract

PURPOSE:To prevent the vibration of a pump which is a driving source from being transmitted to other parts by mounting the pump to an oil level gage via a buffer material. CONSTITUTION:When an external force in applied to the pump 3 of, for exam ple, an oil hot air heater, the same force is also applied to a york 4. At this time, since the pump 3 is mounted to an oil level regulator 5 via O-rings 30a and 30b and a buffer cylinder 32 and especially the buffer cylinder 32 is com pressed in a circumferential direction or gaps are reduced, the buffer cylinder 32 is not largely rotated even though an external force is applied and therefore a shoulder bolt 22 and the york 4 are not brought into direct contact with each other. Thus, a vibration above 1 KHz particularly offensive to the ear is not transmitted.

Ｈｚ以上の振動を伝えることがない。Note that the combustion process of the oil hot air heater is the same as that of the conventional example shown in FIG. 2, so a description thereof will be omitted. Now, for example, when an external force is applied to the pump (3) of a warm air heater, the yoke (
A similar force is also applied to 4). At this time, the pump <3> is connected to the O-rings (30a), (30b) and the buffer tube (
It is attached to the oil level regulator (5) through the oil level regulator (5), and the buffer cylinder (32) in particular is compressed in the circumferential direction or has a small gap, so it does not rotate significantly even if external force is applied. Therefore, the stepped screw (22) and the yoke (4) do not come into direct contact with each other.For this reason, the IK is particularly unpleasant to humans.
It does not transmit vibrations higher than Hz.

Since it is configured so that it cannot be touched, it is possible to reduce high-frequency sounds that are unpleasant to humans at low cost and reliably.
