Patent number: 7533690Abstract: A multifunctional regulator provides a housing having an inlet passage joined with an outlet passage through a poppet valve. The housing has a control diaphragm separating the control chamber into a first volume and a second volume and depending on the differential pressure between the two volumes, the diaphragm will push open the poppet valve. Pressurizing and depressurizing valves join the first volume with the inlet and outlet passages, whereby, with an inlet pressure level within the inlet passage greater than an outlet pressure level within the outlet passage, and with the pressurizing valve admitting the inlet pressure level to the first volume, the diaphragm is displaced into the second volume thereby forcing the poppet valve to open and thereby raising the outlet pressure toward the inlet pressure with fluid flow from the inlet to outlet passages.Type: GrantFiled: July 7, 2006Date of Patent: May 19, 2009Assignee: Stanford Mu CorporationInventors: Robert H.

Patent number: 5868375Abstract: A valve construction relies upon solenoid-driven axial elongation of an annular magnetostrictive core element for opening displacement of an elongate poppet-valve member that is carried within the annulus of the core element. A first stiffly compliant preload independently urges the poppet-valve member into its seated position of lock-up at valve closure, and a second stiffly compliant preload independently prestresses the annular magnetostrictive core element into a fixed referencing abutment with valve-body structure. The currently preferred material of the core is Terfenol-D, which offers a strong elongation response to inductively coupled excitation. The elongation response is sufficient to serve the purposes of (1) closing a pretravel clearance prior to a flange engagement with the poppet-valve member and (2) also, via the flange engagement, displacing the poppet-valve member out of its normal valve-closing engagement with the valve seat.Type: GrantFiled: January 31, 1997Date of Patent: February 9, 1999Assignee: Marotta Scientific Controls, Inc.Inventors: Robert H. Reinicke, Derek Tate Schappell

Patent number: 5611516Abstract: In a preferred ball-valve construction, a valve body has spaced inlet and outlet ports on an axis of flow that is controlled by an interposed ball; the ball is rotatable about a body-fixed axis which intersects the axis of flow at the geometric center of the ball. In the closed condition of the valve, an annular valve-seat member associated with one of the ports has circumferentially sealed contact with the ball. The annular valve-seat member is guided for axial displaceability into and out of its engageability with the ball, and actuation of the valve utilized coordination of valve-seat displacement with ball rotation such that valve-seat engagement with the ball is only for the closed condition of the valve, and such that, valve-opening rotation of the ball can occur only while the annular valve-seat member is in axial-clearance relation with the ball. Various embodiments are disclosed.Type: GrantFiled: March 27, 1995Date of Patent: March 18, 1997Assignee: Marotta Scientific Control, Inc.Inventors: Robert H. Reinicke, Joseph M. Cardin, Arnold Dalene

Patent number: 5501425Abstract: A valve for fail-safe return to its normally closed condition relies upon solenoid-driven elongation of a magnetostrictive core element, for opening displacement of a valve member, and also relies upon a continuously available, stiffly compliant preload of the valve member into its position of lock-up at valve closure. The currently preferred material of the core is Terfenol-D, which offers a strong elongation response to inductively coupled excitation. The elongation response is sufficient to serve the purposes of driving a poppet-valve member from closed to open position, with a relatively short time constant, as well as to permit a closed condition of the valve wherein the driving end of the core is effectively disconnected from the poppet-valve member, so that the prestressed stiff compliance can alone be operative on the poppet-valve member for fail-safe closure of the valve.Type: GrantFiled: September 21, 1994Date of Patent: March 26, 1996Assignee: Marotta Scientific Controls, Inc.Inventors: Robert H. Reinicke, Derek T. Schappell

Patent number: 5464041Abstract: A multiple-valve system is transiently electromagnetically actuated by a single electrical winding, for concurrent change of state for each of the multiple valves, and a permanently magnetized portion of involved magnetic circuitry serves to latch both valves in the operative state into which they have been actuated. The preferred embodiment is based on valve-body structure which is a unitary consolidation of plural slabs of magnetic material in alternation with slabs of non-magnetic material. An electromagnetic actuator includes a U-shaped core having pole faces secured to the uppermost slab, in confronting relation with valve members of magnetic material. A first polarized magnetic-latch circuit exists via the U-shaped core, together with the valve members and a magnetized body slab when in valve-open condition. A second polarized magnetic-latch circuit exists via the magnetized slab, the valve members and another magnetic slab, when the system is in valve-closed condition.Type: GrantFiled: February 14, 1994Date of Patent: November 7, 1995Assignee: Marotta Scientific Controls, Inc.Inventor: Robert H.

Patent number: 5404908Abstract: A magnetically linked twin-valve assembly is electromagnetically actuated in response to excitation of a single solenoid winding. Valve-body structure features relatively thick non-magnetic and magnetic slabs which are bonded into a consolidated body block, in laminated alternation, prior to machining the same for dual-valve purposes. Two spaced guide bores through the body block accommodate movement of separate valve members of magnetic material; the upper end of each of these valve members is upwardly exposed in confronting relation with one to the exclusion of the other pole face of the U-shaped core of an electromagnet, whereby a single magnetic circuit, established by the U-shaped core and the valve members, relies upon the middle slab of magnetic material to complete the circuit by magnetically linking both valve members. Inlet and outlet flows of pressure fluid pass through separate chambers formed primarily in the lowermost slab on the respective guide-bore alignments.Type: GrantFiled: February 14, 1994Date of Patent: April 11, 1995Assignee: Marotta Scientific Controls, Inc.Inventor: Robert H.
