In its initial years, Edwards Vacuum imported vacuum equipment from Germany's Leybold. [ 2 ] [ 3 ] A freeze-drying method using vacuum chambers was patented in the 1930s. During World War II, the technology was further perfected and expanded to freeze-dry instant coffee, but also blood plasma and penicillin.

Note that modern pumps have an area contact between rotor and stator (and not a line contact). 1. pump housing 2. rotor 3. vanes 4. spring. A rotary vane pump is a type of positive-displacement pump that consists of vanes mounted to a rotor that rotates inside a cavity. In ...
M7 Aerospace LP is an aerospace company with its headquarters on the property of San Antonio International Airport in Uptown San Antonio, Texas, United States. [1] [2]M7 is the successor organization to Fairchild Dornier Aviation, having bought much of that firm's assets out of bankruptcy.
In 1994, Degussa sold Leybold to the Swiss Oerlikon Bührle Group, which combined Leybold with the Balzers AG, which was already in their possession, to form the Balzers and Leybold Group. The merger of these companies resulted in the world's largest vacuum and surface technology company with around 6 500 employees, generating sales of DEM 1.8 ...

An Eaton M62 Roots-type supercharger is visible at the front of this Ecotec LSJ engine in a 2006 Saturn Ion Red Line.. The Roots-type blower is simple and widely used. It can be more effective than alternative superchargers at developing positive intake manifold pressure (i.e., above atmospheric pressure) at low engine speeds, making it a popular choice for passenger automobile applications.
Liquid-ring systems can be single- or multistage. Typically a multistage pump will have up to two cascaded compression stages on a common shaft. In vacuum service, the attainable pressure reduction is limited by the vapor pressure of the ring-liquid. As the generated vacuum approaches the vapor pressure of the ring-liquid, the increasing volume ...
Cutaway side-view diagram of an axial piston pump 3-D rendering of an axial piston pump with the parts labeled Animation of an axial piston pump in operation. An axial piston pump has a number of pistons (usually an odd number) arranged in a circular array within a housing which is commonly referred to as a cylinder block, rotor or barrel.
