Abstract: A variable capacity vane pump is provided, the pump having a pump control ring which is moveable to alter the capacity of the pump and the pump can be operated at either of at least two selected equilibrium pressures. The pump ring is moved by at least first and second control chambers, the control chambers abutting the control ring such that pressurized fluid supplied to them acts on the pump control ring to move the pump control ring to reduce the volumetric capacity of the pump. When pressurized fluid is supplied to only one control chamber, the pump operates at a first equilibrium pressure and when pressurized fluid is also supplied to the second chamber, the pump operates at a second equilibrium pressure. If desired, pressurized fluid can also be supplied only to the second control chamber to operate the pump at a third equilibrium pressure and/or additional control chambers can be provided if required.

Abstract: A pump system includes pump having a control feature which, responsive to a supply of pressurized working fluid, reduces the pressure of the working fluid pressurized by the pump. The control feature is connected to the output of the pump by a regulating valve. The control feature receives pressurized working fluid to decrease the output of the pump in response to the pressure of the supplied working fluid. A regulating valve selectively connects the pressurized working fluid to the control feature. The regulating valve has a control port to receive pressurized working fluid from the pump to urge the valve to a closed position against a biasing force. A controllable valve is operable to interrupt the supply of pressurized working fluid to control port to alter the output pressure of the pump.

Abstract: A variable displacement vane pump which includes an enhanced discharge port. The enhanced discharge port reduces areas of high pressure in the discharge port which would otherwise occur as the pressurized working fluid reverses its direction of flow to enter the discharge port. By reducing the areas of high pressure, the back torque on the pump rotor is reduced and the energy efficiency of the pump is enhanced. In one embodiment, the pivot for the pump control ring is located radially outwardly from a conventional location, to allow for a discharge recess to be formed in the control ring, adjacent the discharge port, and extending past the pivot to the pump outlet. In a second embodiment, the discharge recess is formed in the control ring around the pivot and a seal is provided on the control ring to inhibit leakage of pressurized working fluid past the control ring. In a third embodiment, a secondary discharge port is provided adjacent the discharge recess formed in the control ring and pressurized working fluid in the discharge recess can exit the discharge recess through the secondary discharge port which is in fluid communication with the pump outlet.

Abstract: A method of administering a network comprises the steps of: detecting the occurrence of a triggering event alerting an administrator to the presence of a user entity on the network, the triggering event being selected from the group consisting of: (i) allocation of a network address to the user entity; (ii) alteration of the user entity's network address; (iii) an action by the user entity causing resolution between a network address and an identifier; (iv) association of the user entity's network address and an identifier. Upon detecting such an event, the user entity having the network address is scanned for vulnerabilities by sending at least one outward packet to it, for example seeking to establish a connection on a particular port, and the response, if any, is then used to determine whether is vulnerable to known malicious code.

Abstract: A vane pump with a reduced rotor diameter is provided. The reduced rotor diameter allows a reduction in the overall size of the pump which allows the pump to be used in circumstances wherein sufficient packaging volume does not exist for conventional vane pumps. Further, the reduced rotor diameter permits operation of the pump at a higher speed, in comparison to conventional vane pumps, for a given working fluid and pump rate. The rotor includes an integrally formed drive shaft and a cylindrical rotor head. Both fixed displacement and variable displacement embodiments are shown.
