Abstract:
A combustion tool (10) is provided, including a combustion power source (14) with a reciprocating valve sleeve (36) moving between a rest position in which a combustion chamber (18) is open, and a closed position in which the combustion chamber is sealed, a control system (66) operatively connected to the power source, and a trigger switch (26) connected to the control system and providing operator interface with the control system. The control system is configured such that operator manipulation of the trigger switch is the only operator initiated movement required for initiating repetitive spark generation.
Abstract:
Eine insbesondere für den Einsatz als Einspritzsystem in Nageltreibgeräten geeignete Vorrichtung zur dosierten Abgabe einer Flüssiggasformulierung umfasst einen druckstabilen Behälter (1) mit einem Bördelrand (2), auf dem ein ein Abgabeventil (4) enthaltender Ventildeckel (3) dicht befestigt ist. Der Behälter (1) ist mit zwei getrennten Kammern (6,7) ausgestattet, deren eine die Flüssiggasformulierung (F) aufnimmt und mit dem Abgabeventil (4) kommuniziert und deren andere ein unter Überdruck stehendes Treibmedium (L) enthält. Im Behälter (1) ist ein dichtend beweglicher Kolben (5) vorgesehen, der den Behälter in die beiden Kammern (6,7) unterteilt. Das Treibmedium (L) ist Druckluft in Kombination mit einer geringen Menge Flüssiggasformulierung (F ü ). Der Bördelrand (2) des Behälters (1) ist als Innenbördelung ausgebildet. Der Kolben (5) ist mit einer Einwegventilanordnung ausgestattet, welche ein Überströmen von Flüssiggasformulierung (F) von der die Flüssiggasformulierung (F) enthaltenden Kammer (6) in die das Treibmedium (L, F ü ) enthaltende Kammer (7) ermöglicht. Die Abgabevorrichtung ist konstruktiv besonders wenig aufwendig und kann auf einfachste Weise kostengünstig hergestellt und befüllt werden.
Abstract:
Gas cartridge adapter for fixing the same to a transmission and combustion chamber filling member of a gas fixing device and for disconnecting the same from the member. The adapter (102) comprises a central tubular body (106) extending on one side with an abutment and fixing base (105) on the cartridge and, on the other side, with two fixing legs (108, 109) on an intermediary nose piece (4) of the transmission and filling member able to be hinged for ensuring the fixing operation, disconnecting and ejecting wings (115, 116) being additionally provided. The disconnecting and ejecting wings (115, 116) are arranged for opening the fixing legs (108, 109) before driving them into translation.
Abstract:
A new and improved combustion chamber (102) and cooling system for a fastener-driving tool (100) wherein a new and improved tangentially oriented, vortex induced fuel-injection system is operatively associated with the tool's combustion chamber (102). In addition, a new and improved trigger-controlled valve actuating system, such as, for example, a switch-operated, solenoid-actuated valve-controlling system (154), is incorporated within the tool (100) so as to ensure the rapid operation of the intake and outlet valve structures (106, 146). Still further, a sealed, liquid evaporative or liquid recirculating cooling system is integrally incorporated within the tool housing.
Abstract:
An aerosol container of the nail gun includes a container body, a valve body (3), a valve core (5), a sealing ring (4) and an elastic piece (8). The upper end of the valve body (3) is flush mounted in the container body. The lower end of the valve body (3) is in tight connection with an inner bag (1). The valve core (5) is installed in the valve body (3). The upper end of the valve core (5) forms a tubular valve nozzle. An inner circumference B and an outer circumference A are manufactured on the upper end of the valve body (3), and the inner circumference B is lower than the outer circumference A. The lower end face of the sealing ring (4) abuts against the upper end of the inner circumference B, and the margin of the sealing ring (4) is contained in the outer circumference A. When the valve core (5) is in the first axial position, the upper necking section C and the lower necking section D is respectively located inside and out side of said boss, and the upper surface and the lower surface of the sealing ring (4) respectively abut closely to the boss and the inner circumference B; when the valve core (5) is in the second axial position, the upper necking section C locates on the opening of the boss, and the upper surface of the sealing ring (4) departs from the lower surface of the boss. Therefore, it's convenient to fill, and it's effective to prevent gas leakage.
Abstract:
A combustion chamber system, for use in connection with internal combustion powered fastener-driving tools, comprises a dual-level combustion chamber comprising first and second pre-combustion and main combustion chambers, and a dual-level rotary valve mechanism which is operatively connected to the dual-level combustion chamber so as to control the intake of the air/fuel mixture as well as the scavenging or purging of the exhaust gases or combustion products. The first and second pre-combustion and main combustion chambers are also separated by a plate having a plurality of apertures defined therein whereby multiple jets or flame fronts are defined throughout the combustion chamber system.
Abstract:
A fastener-driving tool includes a combustion power source (14) configured for driving a driver blade (46) linearly towards a workpiece, and an electrical power source (80) associated with the combustion power source for rotationally driving the driver blade upon completion of the linear travel, both power sources being disposed in the tool.
