  • Patent number: 11867277
    Abstract: A resonator having a cavity and an opening is formed. The cavity is formed between a transaxle case and a facing wall, of a first housing case, that faces the transaxle case. The opening is configured such that the cavity is partially opened to a lateral side through the opening. A volume of the cavity and a volume of the opening are set such that a resonance frequency of the resonator is lower than a natural frequency of the facing wall of the first housing case. Since the resonance frequency of the resonator is lower than the natural frequency of the facing wall, even when the facing wall vibrates at the natural frequency, the cavity does not resonate. Hereby, abnormal noise caused from the transaxle can be reduced.

    Abstract: An adjustment device for a water delivery unit includes a valve body extending along a longitudinal axis with a water inlet and outlet, a shutter arrangement to control water flow from the inlet to the outlet, a first actuating member movable along the longitudinal axis to arrange shutter arrangement into opening and closing positions to respectively enable/disable the passage of water and a second actuating member rotatable about the longitudinal axis to vary the opening position of the shutter arrangement to adjust a flow rate of the water exiting the valve body. The device has a manual control member coupling with the first and second actuating members and configured to receive a manual action by a user for opening, closing and adjusting the flow rate of the water. The second actuating member cooperates with the shutter arrangement through a cam arrangement for varying the opening position of the shutter arrangement.

  • Patent number: 11867314
    Abstract: There is provided a method of energising a solenoid of a valve assembly, comprising the steps of applying a positive over boost voltage to the solenoid to actuate a moveable plunger to open or close a flow path through the valve assembly, and then applying a negative braking voltage to brake the movement of the plunger during movement of the moveable plunger. There is also provided a method of energising a solenoid of a valve assembly, the method comprising the steps of receiving a demand signal to actuate the valve, applying a wait time after receipt of the demand signal, applying a positive over boost voltage across the solenoid to actuate a moveable plunger to open or close a flow path through the valve assembly, monitoring the solenoid closure time, and adjusting one or more input variables in order to control the solenoid closure time.

  • Patent number: 11867315
    Abstract: A method for verifying the operation of a safety valve having a valve member and a positioner for controlling the position of the valve member is proposed. The safety valve is part of a plant on which a process with a process medium runs. The plant has a sensor for monitoring the state of the plant, the process and the process medium. A sensor's measured value is used to determine a point in time during ongoing plant operation at which the operability of the valve can be verified in the context of a partial stroke test. The test can also be monitored with the sensor and the stroke range traversed therein can be dynamically adapted to the state. The test can thus be performed safely during operation and with an optimized stroke range. The method enables more frequent testing of and more reliable statements about the operability of the safety valve.

  • Patent number: 11867318
    Abstract: A high-pressure fluid discharge device that can adapt to large flow rates while being small in size has a diaphragm valve body that cooperates with a valve seat provided to a body to switch between communication and blocking between a first flow path and a second flow path. A pilot chamber and a valve chamber joined to the first flow path are sectioned by the diaphragm valve body, and the diaphragm valve body is provided with a pilot passage allowing communication between the valve chamber and the pilot chamber. The diaphragm valve body is also provided with a pilot-type spool valve that switches between communication and blocking between the pilot chamber and an excretion port.

  • Patent number: 11867319
    Abstract: A microfabricated valve with no moving parts. In one embodiment, the valve includes a reservoir of a liquid that is in fluid communication with an outlet channel having a throat that is less than 100 microns wide. Preferably, the channel is an elongated slit. The configuration of channel is adapted and configured such that surface tension of the liquid prevents flow out of the channel. A heater increases the temperature of the meniscus of the fluid, until a portion of the fluid is ejected from the channel. The ejection of the fluid creates both a thrusting effect and a cooling effect.

  • Patent number: 11867320
    Abstract: In a polymeric microfluidic valve, an adhesion control surface with discrete micro- or nano-scale structured surfaces are separated by fluid filled voids at an interface between an elastomeric membrane seals against a substrate layer. The structured surfaces reduce adhesion between the membrane layer and the substrate layer and prevent permanent bonding, while at the same time providing a good balance of adhesion at the valve seat to provide a sealing engagement. Microstructured adhesion control surfaces on and around valve bodies permit opening the valve, by reducing contact surface area.

  • Patent number: 11867322
    Abstract: A method of connecting a conduit to a subsea structure is provided. In the disclosed method, a tensioning member is provided on the conduit and attached to the conduit at two locations proximate a first end of the conduit. The tensioning member is used to maintain a curvature formed in the conduit between the two locations e.g. by deflecting a portion of the conduit. A first end of the conduit is engaged with a guide assembly provided adjacent to the subsea structure, and tension in the tensioning member is released to adjust the axial position of the first end of the conduit to enable direct connection between the conduit and the subsea structure. A method of disconnecting a conduit from a subsea structure, and a system for connecting a conduit to a subsea structure are also provided.
