Abstract
A fluidic connector comprises an independent adjunct to a pneumatic tool and is adapted to be fluidically interposed between an air supply hose and a fitting of the pneumatic tool. The connector comprises a piston-type valve member. Exhaust generated from each fastener firing operation or cycle maintains the piston-type valve member at a first position so as to permit the incoming air supply to reach the tool, however, if the tool is not fired within a predetermined period of time, the piston-type valve member is automatically moved to a second position which prevents the air supply from reaching the tool thereby disabling the same.
Claims25
A fluidic connector for providing a fluidic connection between a supply of air and a pneumatically-operated tool, comprising:
- a housing;
- first connection means integrally formed upon said housing for connection to an air supply;
- second connection means integrally formed upon said housing for connection to a pneumatically-operated tool;
- a fluid circuit defined within said housing for providing a fluid flow path between said first connection means and said second connection means so as to conduct air from the air supply to the pneumatically-operated tool;
- and
- a valve assembly, disposed within said housing and operatively associated with said fluid circuit defined within said housing, for permitting air to flow from the air supply to the pneumatically-operated tool when said valve assembly is disposed at a first position as a result of the pneumatically-operated tool being operated within a predetermined period of time such that the pneumatically-operated tool is operationally enabled, and for terminating the air flow from the air supply to the pneumatically-operated tool when said valve assembly is automatically moved to a second position as a result of the pneumatically-operated tool not having been operated within the predetermined period of time so as to render the pneumatically-operated tool operationally disabled.
In combination with a pneumatically-operated tool, a fluidic connector for providing a fluidic connection between a supply of air and a pneumatically-operated tool, comprising:
- an air supply;
- a pneumatically-operated tool;
- a housing;
- first connection means integrally formed upon said housing for connection to said air supply;
- second connection means integrally formed upon said housing for connection to said pneumatically-operated tool;
- a fluid circuit defined within said housing for providing a fluid flow path between said first connection means and said second connection means so as to conduct air from said air supply to said pneumatically-operated tool;
- and
- a valve assembly, disposed within said housing and operatively associated with said fluid circuit defined within said housing, for permitting air to flow from said air supply to said pneumatically-operated tool when said valve assembly is disposed at a first position as a result of said pneumatically-operated tool being operated within a predetermined period of time such that said pneumatically-operated tool is operationally enabled, and for terminating said air flow from said air supply to said pneumatically-operated tool when said valve assembly is automatically moved to a second position as a result of said pneumatically-operated tool not having been operated within the predetermined period of time so as to render said pneumatically-operated tool operationally disabled.
