  • Publication number: 20170219077
    Abstract: A compact planetary differential gear set includes first (130A) and second (130B) sun gears, a first set (200A) and a second set (200B) of planet gears (220), and a carrier (160) with a ring gear (190). Enmeshing gear pairs (210) are formed from one planet gear from each set. The first and second planet gear sets enmesh the first and second sun gears, respectively. The ring gear does not extend into an annular region containing the planet gears thereby allowing four or more gear pairs to compactly fit into the annular region. The carrier is a weldment and substantially encloses the sun gears and the planet gears permanently. The differential requires no fasteners or post-weld machining and may have a higher capacity, lower cost, smaller size, lower part number count, and/or lower amounts of material compared with conventional differentials. The differential is suited for motor vehicle applications.

  • Publication number: 20170219085
    Abstract: During the travel of a vehicle, the oil level of lubricating oil is lowered due to the suction by at least a first oil pump and the scraping-up by the rotation of a differential ring gear and so on. In particular, until the oil level becomes equal to or lower than an upper end of a first partition wall, the oil level is lowered due to both the suction by the first oil pump and the scraping-up by the rotation of the differential ring gear and so on, and therefore, a region, that is immersed in the lubricating oil, of the differential device rapidly becomes smaller. Since a suction port of the first oil pump is disposed in a second oil storage portion, the oil level in the second oil storage portion during the travel of the vehicle can be adjusted independently of that in a first oil storage portion.

  • Publication number: 20170219090
    Abstract: When a shift lever is moved to a shift position corresponding to a first gear position etc., the shift lever is urged by its own weight to a neutral position, which is disadvantageous for the shift lever in terms of gear slip-out after shifting. However, a counter mass is moved to a position reached by turning a second predetermined angle, larger than a first predetermined angle corresponding to the neutral position, downward with respect to a vertical line passing through a center of turn of the counter mass. Meanwhile, the shift lever is urged by the weight of the counter mass in the direction away from the neutral position, so that gear slip-out after shifting can be prevented.

  • Publication number: 20170219113
    Abstract: A multifunctional restrictive valve for controlling the flow of water therethrough. The valve has a main body with a flow channel through the main body. The main body receives water upstream thereof through an inlet port and, passes it out through an outlet port at the downstream end of the body. A flow control assembly is located in the flow'channel and includes a temperature sensor/actuator acting on a piston to move, when the temperature sensor heats up the piston, to block water flow control ports. The flow control assembly also includes an override feature wherein the piston is located within a slide and the flow control ports are located in the slide. By moving the slide away from thepiston when the piston is blocking the flow control ports, the temperature sensor and piston may be overridden and flow may resume through the main body.

  • Publication number: 20170219114
    Abstract: A power operated valve for controlling fluid flow is provided with a fail-safe device responsive to failure of the power supply to the valve to shut-off fluid flow. A valve member is coupled to linear actuator for movement towards and away from a closed position for controlling fluid flow through the valve. The linear actuator is held in a control position by the fail-safe device for normal operation of the valve with the power supply on. The fail-safe device responds to failure of the power supply to release the linear actuator. When the linear actuator is released, energy stored n a spring while the linear actuator was held in the control position is released and biases the linear actuator away from the control position causing the valve member to move to the closed position to shut-off fluid flow.

  • Publication number: 20170219120
    Abstract: A miniature fluid control device includes a gas inlet plate, a resonance plate and a piezoelectric actuator. The gas inlet plate includes at least one inlet, at least one convergence channel and a central cavity. A convergence chamber is defined by the central cavity. The resonance plate has a central aperture. The piezoelectric actuator includes a suspension plate, an outer frame and a piezoelectric ceramic plate. A gap is formed between the resonance plate and the piezoelectric actuator to define a first chamber. When the piezoelectric actuator is driven and after the gas is fed into the miniature fluid control device through the inlet of the gas inlet plate, the gas is sequentially converged to the central cavity through the convergence channel, transferred through the central aperture of the resonance plate, introduced into the first chamber, transferred downwardly through the piezoelectric actuator, and exited from the miniature fluid control device.

    Abstract: A miniature pneumatic device includes a miniature fluid control device and a miniature valve device. The miniature fluid control device includes a gas inlet plate, a resonance plate, a piezoelectric actuator and a gas collecting plate. A first chamber is formed between the resonance plate and the piezoelectric actuator. After a gas is fed into the gas inlet plate, the gas is transferred to the first chamber through the resonance plate and then transferred downwardly. Consequently, a pressure gradient is generated to continuously push the gas. The miniature valve device includes a valve plate and a gas outlet plate. After the gas is transferred from the miniature fluid control device to the miniature valve device, the valve opening of the valve plate is correspondingly opened or closed and the gas is transferred in one direction. Consequently, a pressure-collecting operation or a pressure-releasing operation is selectively performed.
