US Patent:

6412457, Jul 2, 2002

Filed:

Aug 28, 1998

Appl. No.:

09/143403

Inventors:

Joseph M. Vorih - West Suffield CT
Kevin J. Kinerson - Vernon CT
Mark A. Israel - Amherst MA

Assignee:

Diesel Engine Retarders, Inc. - Christiana DE

International Classification:

F01L 116

US Classification:

123 9012, 123 9049, 123 9055

Abstract:

The present invention provides a hydraulic actuator for operating an engine valve, which includes a means for controlling the seating velocity of the valve. The design allows for free, unrestricted movement of the actuator piston during opening of the engine valve, and an unrestricted return of the piston and valve until the valve is within a predetermined distance of the valve seat. Once within this predetermined range, the return velocity of the actuator piston and engine valve are limited by the rate at which a fluid may escape through a restriction. The restriction is calibrated to provide the desired maximum valve seating velocity. The invention also provides for automatic lash adjustment.

Assignee:

Thermal Dynamics Corporation - West Lebanon NH

International Classification:

B23K009/00

US Classification:

21912149, 2191215

Abstract:

Plasma arc torches are provided that include a mounting for an electrode and a coolant tube telescopingly mounted on the plasma arc torch to engage and deliver coolant to electrodes of different sizes mounted in the mounting. The telescopingly mounted coolant tube may extend to a closed position in which coolant does not flow when no electrode is mounted in the mounting. The telescopingly mounted coolant tube may further be used to electrically connect a cathodic member with the electrode mounted in the mounting.
