  • Patent number: 9874287
    Abstract: A service valve for a valve body includes a base rotatable between an open orientation and a closed orientation relative to the valve body. When the base is in the open orientation, the service valve allows fluid flow into the valve body through the service valve. When the base is in the closed orientation, the service valve blocks the fluid flow into the valve body through the service valve. The service valve further includes a tab extending from the base. The tab prevents removal of a cover from the valve body when the base is in the open orientation.

    Abstract: A protruding section formed at the one side end of a connector section provided in a valve is inserted into a recessed section formed as part of a valve placement section of a fluid apparatus. The valve is caused to pivot with the inserted portion that serves as a supporting point, and an engaging section formed at the front end of a lever of a hook section formed at the other side end of the connector section is allowed to engage with an engaging protruding section formed as part of the valve placement section of the fluid apparatus. The valve is thus attached to the fluid apparatus.

  • Patent number: 8627851
    Abstract: A multi-position valve assembly including a valve housing, a stator element and a rotor element rotatably mounted about a rotational axis. The valve assembly further includes a pressure adjustment assembly movable between a release position and a stop position, hard stopped relative to the valve housing. The pressure adjustment assembly includes a pressure adjuster device configured to movably cooperate between the rotor element and the valve housing to adjustably generate an axial compression pressure at the rotor-stator interface at a calibrated operating pressure, PC. When the pressure adjustment assembly is oriented in the release position, the axial compression pressure is substantially removed from the rotor-stator interface. In contrast, when the pressure adjustment assembly is oriented in the stop position, the axial compression pressure is substantially reproduced at the calibrated operating pressure, PC.

Each chemical eductor is slidably insertable into an eductor port on the manifold body such that rotation of the chemical eductor is not required for installation. After installation, the orientation of the chemical eductor can be rotatably adjusted so as to avoid interference with adjacent chemical eductors. Delivery of a bulk fluid to each chemical eductor is controlled via a corresponding valve assembly that selectively allows or blocks flow of the bulk fluid from the bulk fluid flow path to the corresponding chemical eductor. The manifold body can include a plurality of individual manifold bodies approximated with a coupling system to define the bulk fluid flow path. Alternatively, the manifold body can comprise a single fabricated body for high pressure operation.

  • Patent number: 6814098
    Abstract: A support structure for a C-ring includes a pair of circumferentially spaced holding members on catch plates. The holding members may be moved individually into the C-ring after the C-ring is mounted within an outer housing. The two holding members thus provide support to an inner periphery of the C-ring. A locking plate has support structure moved between circumferential ends of the housing members, thus providing effective support for the C-ring around its entire inner periphery. In this way, the two parts secured by the C-ring need not be moved relative to each other to insert the C-ring. The clearance or ability to move one of the two parts relative to the other which has been required in the past to mount a C-ring, is not necessary. This makes the inventive C-ring particularly useful for new applications, such as holding a porting sleeve within a valve housing.

  • Patent number: 6769445
    Abstract: A gear meshing with a pinion controls the angle of rotation of a valve element which is brought into sliding contact with a valve seat, thereby controlling the opening and closing of a communicating hole of outflow pipe. During welding the valve seat plate and a housing, a hook portion of an upper portion of the gear is retained by a retaining portion to cause the valve element to be spaced apart from the valve seat. After natural cooling, the pinion is remotely operated by an electric motor to rotate the gear, thereby canceling the holding. A resilient arm causes the gear to be disengaged from the retaining portion by its urging force, brings the valve element into pressure contact with the valve seat, and allows the opening/closing operation to function smoothly.
