  • Patent number: 6668574
    Abstract: A manifold for charging a system which when in use cycles a refrigerant between liquid and gaseous states is disclosed. The manifold includes a housing defining a flow passage extending from an inlet to an outlet. Structure is within the housing to define a capillary in parallel communication with a section of the passage. A refrigerant state control valve is connected to the housing. The valve, when in the open position, enables concurrent refrigerant flow through both the section of the passage and the capillary to charge such a system with refrigerant in a liquid state. The valve when in the closed position sufficiently blocks the section of the passage to cause all refrigerant flow to be through the capillary thereby to enable charging such a system with refrigerant in a gaseous state.

  • Patent number: 5495672
    Abstract: A tube cutter unit in one embodiment with self centering tube cutting and supporting jaws is rotated by a power drive unit for cutting a tube. The jaws are free to engage the tube without spring load. After engagement with the tube, a relatively high load spring is deflected to induce a tube cutting force on the jaws. The amount of deflection of the spring determines the depth of cut. A separate tool operating socket is also rotatably driven with the cutter unit. The cutter unit is coupled to the drive by a one way clutch. The drive is reversible to selective operate the cutter unit. In a second embodiment, a cutter unit without self centering jaws is separated from a power drive for manually operation and connected to the power drive for power operation. The power operator is reversible for selectively operating the cutter unit. The latter cutter unit also does not provide a spring load on the jaws except for providing a cutting force after the jaws engage the tube being cut.

  • Patent number: 5345682
    Abstract: A tube cutter mechanism supports an arm from which a tube supporting anvil extends, the anvil being aligned with the tube cutter mechanism for cutting the supoorted tube. During cutting, an axial force is imposed on the tube and anvil. The arm is formed such that it bends in response to the force, storing energy such that rotation of the tube occurs for more than one revolution of the tube without advancing the cutter wheel. The device is formed of molded glass fiber reinforce nylon, preferably ZYTEL. In a second embodiment, the arm does not bend and the anvil is constructed so as to bend relative to the arm in response to the axial cutting force permitting rotation of the tube during cutting beyond a single revolution without advancing the cutter wheel. The anvil advantageously does not have a cutter wheel for burnishing the tube to remove oxides during cutting.
