ABSTRACT:
A diaphragm type air spring is disclosed, which comprises large and small piston members integrally connected to each other. Large and small outer shells are coaxially arranged with the piston members and integrally connected to each other with a common partition. Each of the large and small outer shells has a diameter larger than that of each of the respective large and small piston members. A diaphragm airtightly connects each of the large and small outer shells to each of the respective large and small piston members. An orifice is formed in the partition so as to communicate a small air chamber defined by the small piston member, small outer shell, diaphragm and partition with a large air chamber defined by the large piston member, large outer shell, diaphragm and partition, whereby a load of a vibration system is born with the large outer shell integrally connected thereto.
