  • Patent number: 7121523
    Abstract: Particularly in an engine that has been inactive for a substantial period of time at a cold temperature, fluid forces acting on moving members, such as electronically-activated fluid control valves, may be significant until the engine warms up. A way to reduce the fluid forces and their detrimental effects is to reduce the volume of fluid which are creating the fluid forces, including venting all or some of this fluid to drain. Additionally, fluid that gathers can be drained away. In order to accomplish such venting, the present disclosure includes a fluid control valve having a body with at least one fluid passage connected to a bore, a movable member in the bore, an actuator connected to the movable member to move the movable member, and at least one vent passage opening into the bore between the fluid passage and the actuator. The disclosure may include additional drain passages to drain away gathered fluid from actuating components.

  • Patent number: 7093625
    Abstract: Apparatus and method for filling spaced apart cavities with particulate material include a transport for moving the cavities along a path of travel. The cavities are partially filled with particulate material at an upstream location while applying vacuum underneath each cavity during such partial filling. The partially filled cavities are then completely filled with a downstream deposit of particulate material while applying vacuum to the upper sides of each cavity during such filling. The combination of vacuum applied underneath the cavity during partial fill and vacuum applied to the top sides of the cavity during complete fill produces approximately 100% cavity fill with minimal extraneous scatter of particulate material.

  • Patent number: 7070162
    Abstract: A valve actuating apparatus for control of fluid flow that has a housing having a valve body with a first port and a second port that extend through the housing. In one embodiment the valve actuating apparatus also has a toggle valve assembly that includes an armature, at least one sealing surface connected to the armature, and a spring biasing the armature to a first position where the sealing surface closes the first port.
