  • Patent number: 8985549
    Abstract: An electromagnetic valve (32) for use in controlling fluid flow between first and second passageways (P1, P2) in a hydraulic valve block (4), includes a valve body (51). The valve body (51) defines a central axis (A), has a central opening (51A) therethrough, has a lower end (54) adapted to be inserted into a bore (19) of the valve block (4), and is provided with a lower cylindrical opening (70). An armature (56) is axially movable within the valve body (51) and is biased by a spring in one axial direction (57A). A closing element (88) is carried by a lower end (54) of the armature (56). An electromagnetic coil (64) coaxially surrounds the armature (56) and is operable to effect axial movement of the armature (56) in an axial direction opposite the one direction (57B). A valve seat member (62) is carried by the lower end (54) of the valve body (51) and has an orifice (98) providing fluid flow between the first and second valve block passageways (P1, P2).

  • Patent number: 8978641
    Abstract: A low cost mass-produced solar module that extracts both electricity and heat from the sun. One or more reflectors held by a frame reflect the sun's heat into an absorber. Each reflector rotates about its axle to keep its reflected solar energy focused on the absorber. In one embodiment, solar heat is focused to heat fluid that flows to thermodynamic engines that convert the heat to electricity. Engine waste heat is also captured for use as building heat, home hot water or industrial process heat. In another embodiment, solar heat is focused onto photovoltaic devices that directly convert light into electricity. The fluid that cools the photovoltaic devices can be used for building heat, home hot water or industrial process heat. The frame shields the reflectors from ambient wind loads, supports reflector axles accurately and simplifies installation on roofs or walls of buildings.

  • Patent number: 8827236
    Abstract: A solenoid-operated control valve has a primary piston and a secondary piston located within a sleeve, and a solenoid coil disposed about the sleeve to effect movement of the primary piston. The primary and secondary pistons are independently movable along the sleeve. The secondary piston defines a pilot orifice connected with a center passage. The primary piston has a seal pin that extends into the pilot orifice of the secondary piston to block and unblock the center passage with movement of the primary piston in relation to the secondary piston. A spiral cut scarf ring disposed about the secondary piston is in contact with both the secondary piston and the sleeve to allow controlled leakage of a fluid through the valve via space between the secondary piston and the sleeve. The leaked fluid is permitted to collect in a cavity between the primary and secondary pistons.
