PRESSURE MEDIUM PASSAGE DEVICE IN CYLINDER |
摘要 |
<p>An arrangement wherein fluid pressure passageways opening into inner chambers of a cylindrical housing of a valve device, are formed between abutting faces of two axially aligned cylindrical portions comprising the housing. The opening or passageway between the abutting faces is formed by complementarily engaging saw-like teeth formed around the annular abutting faces of the two housing portions. This arrangement provides a smoother surface over which the sealing gasket on a valve member must ride, thus resulting in less wear and tear on the gasket.</p> |
