Later, it led to the founding of the Guy Disc Valve Motor Co . in Ypsilanti.
2.
The result was the 1953 IFA racer that featured a rotary disc valve-as per Zimmermann-from 1953.
3.
It was the first successful tilting-disc valve.
4.
However investigations have found that several tilting disc valves and only one bileaflet valve, the Edwards-Duromedics, generate cavitation within the physiological range.
5.
At about that time, grave problems were encountered by Shiley with the increasing number of sudden failure of the Bjork-Shiley mechanical disc valve.
6.
Tilting-disc valves have flow separation behind the valve struts and disc as a result of a combination of high velocity and stagnant flows.
7.
Compared with the Edwards valve, which had the shape of a little ball, the disc valve needed much less space within the heart when implanted.
8.
In 1968, he collaborated with American engineer Donald Shiley to develop the first " monostrut tilting disc valve " used to replace the aortic or mitral valve.
9.
In April, 1921, Guy and Heinz left the Apex Motor Corporation, obviously with the support of Apex, to found the " Guy Disc Valve Motor Co . " in Ypsilanti.
10.
Loop scavenging, disc valves and expansion chambers worked in a highly coordinated way to significantly increase the power output of two-stroke engines, particularly from the Japanese manufacturers Suzuki, Yamaha and Kawasaki.
