Dividing Into Parallel Flow Paths With Recombining Patents (Class 137/599.01)
  • Patent number: 9708057
    Abstract: An active landing gear damping system and method for decelerating a vehicle during a terrain impact event, such as an aircraft landing or crash. The system monitors aircraft state data and terrain information to predict an impact of the vehicle with the terrain. The system can then determine a target damper force for each landing gear of the vehicle and a predicted damper velocity at the time of impact. Each landing gear can include an adjustable damper valve, wherein adjustment of the damper valves varies the damping coefficient of the respective dampers. The system can adjust valves of the respective dampers to provide the target force based on the predicted damper velocity. After an impact begins, the system can continuously monitor and adjust the valve to maintain the target force.

  • Publication number: 20150000772
    Abstract: A valve device includes a first passage opened by a first valve member, a second passage opened by a second valve member, and a specific chamber in which an asymmetrical state is caused. When the second valve member is open, escape fluid flows through the specific chamber just before flowing into a second passage and collides a collision part located in the specific chamber. The escape fluid flowing in the specific chamber collides the collision part and is divided into two divided flows, and the two divided flows are joined again at downstream of the collision part. In the asymmetrical state, a difference is caused in a pressure loss between the two divided flows. By the asymmetrical state, a pressure loss as an entire of the specific chamber decreases, and frequency in using a valve mechanism can be reduced. Therefore, the valve mechanism can be used longer without omitting the specific chamber.

  • Patent number: 8418714
    Abstract: A pressure type flow rate control apparatus is provided wherein flow rate of fluid passing through an orifice is computed as Qc=KP1 (where K is a proportionality constant) or as Qc=KP2m(P1?P2)n (where K is a proportionality constant, m and n constants) by using orifice upstream side pressure P1 and/or orifice downstream side pressure P2. A fluid passage between the downstream side of a control valve and a fluid supply pipe of the pressure type flow rate control apparatus comprises at least 2 fluid passages in parallel, and orifices having different flow rate characteristics are provided for each of these fluid passages, wherein fluid in a small flow quantity area flows to one orifice for flow control of fluid in the small flow quantity area, while fluid in a large flow quantity area flows to the other orifice for flow control of fluid in the large flow quantity area.

  • Patent number: 8394051
    Abstract: A device for detecting pressure and/or temperature changes in a fluid-channel and method thereof are disclosed. The device includes a main duct with an inlet and an outlet, a branch ductwork with a first branch end branching off the main duct downwards the inlet and with a second branch end discharging into the main duct upwards the outlet, and at least one dead-end channel with a first end that branches off the branch ductwork and a second closed end. The dead-end channel is adapted to trap a gas bubble within the dead-end channel when the device is primed or filled with a liquid fluid, wherein the gas bubble changes its size or position if a change in pressure or temperature occurs in the device.

  • Publication number: 20130025719
    Abstract: A connecting tube with a flow rate stabilizer of the present invention includes a flow rate stabilizer and a connecting portion. The flow rate stabilizer has a main body and an elastic ring. The elastic ring is received in the receiving groove of the main body. The connecting portion is divided into a first part and a second part. As such, the present invention uses the elastic ring moving in the receiving groove. Pushing by the water, the elastic ring is able to move in the receiving groove so as to obstruct the flow way partially, and the flow rate would be stable. The structure of the connecting portion enables the present invention to be adapted to various water pipes. As such, manufacturing is uncomplicated, and lifetime is prolonged. Therefore, the present invention is more competitive.

The basket has a cylindrical sidewall screen with profiled wires arranged around bars that extend from the base. The basket also has a top screen attached to the sidewall screen. The top screen has wires arranged across a plurality of bars. Fluid flow passing through the screens is directed by the profiled wires and the bars. Below the top screen, a baffle plate diverts the fluid flow passing through the top screen to the periphery of the top plate. Inside the basket, a flow modifier has a vanes attached to the base and disposed radially around the base's opening. At least some of the vanes have cross-tees extending from the vane's sides to break the radially directed flow inside the basket.
