  • Patent number: 8696337
    Abstract: A plunger type water pump mainly comprises a cavity body, a rotary main shaft and a plunger flow-distributing unit. The plunger flow-distributing unit comprises a flat valve assembly, a plunger-shoe assembly and a supporting valve assembly. The plunger-shoe assembly divides the cavity body into a high-pressure cavity and a low-pressure cavity independent of each other. The high-pressure cavity is in fluid communication with the flat valve assembly; and the low-pressure cavity is in fluid communication with the supporting valve assembly. The high-pressure water and the low-pressure water are independent of each other. This arrangement ensures a high volumetric efficiency of the water pump under ultra-high-pressure conditions and provides fluid support and lubrication for a friction coupling under high-speed heavy-load conditions to prolong the service life of the water pump.

  • Publication number: 20130264103
    Abstract: The present disclosure discloses a bonding structure, wherein a plurality of first bonding pads is located on a first substrate. A second substrate is disposed to partially face first substrate. A plurality of second bonding pads is located on second substrate with one side, and partially overlapped with the first bonding pads with the other side to form a bonding region and a peripheral region located in the periphery of the bonding region. An anisotropic conductive film is disposed between first bonding pads and second bonding pads. The anisotropic conductive film includes a plurality of conductive particles. At least one move structure is disposed in the periphery region. When the conductive particles of the anisotropic conductive film are moving during the bonding process, the groove structure can accommodate the conductive particles moved hereto.
