摘要： The present invention is a scroll pump comprising two intermeshing scrolls arranged so that on relative orbital movement of the scrolls gas is pumped from an inlet to an outlet. The scrolls have a plurality of successive scroll wraps I, II, II, IV, V, VI between the inlet and the outlet. There is a single-start condition in which fluid is pumped from the inlet to the outlet along a single flow path extending through each of the scroll wraps in succession and a multi-start condition in which fluid is pumped from the inlet along a plurality of flow paths which extend in parallel through radially adjacent scroll wraps and converge to a single flow path prior to the outlet. A valve arrangement is operable for switching the scroll pump between the single-start and the multi-start conditions.

摘要： The present invention relates to a multi-stage vacuum pump comprising: first and second half-shell stator components and first and second end stator components which when assembled define a plurality of pumping chambers. The half-shell components are assembled together along respective pairs of mutual engaging longitudinal faces and the end stator components are assembled at the ends of the half-shell components at respective pairs of mutual engaging end faces. An annular channel is counter-sunk in at least one end face of each pair of mutual engaging end faces for receiving respective sealing members for sealing between the half-shell components and the end stator components. Recesses are counter-sunk at the end portions of the longitudinal faces for receiving a sealant and supports provide support for the annular sealing members at the recesses when the annular sealing members are received in the annular channels to resist protrusion of the annular sealing members into the recesses when compressed between mutually engaging end faces.

摘要： In situations where a vacuum system is suddenly overloaded, there is a risk of mechanical damage being sustained, for example, bearing damage, gear slippage or rotor and/or stator collisions. Sudden overloads can also lead to electrical damage, for example, over-currents or power surges. Therefore a pressure regulating apparatus is provided for use in a vacuum pumping system having an inlet, an outlet and a conduit interposed between, and in fluid communication with, the inlet and the outlet, wherein the cross-sectional area of the conduit is greater than that required to meet the conductance requirements of the inlet and the outlet.

摘要： A scroll compressor includes two scrolls 40, 46 having respective scroll plates 42, 48 and respective scroll walls 44, 50. The scroll walls intermesh so that on relative orbital movement of the scrolls, a volume 52, 54 of gas is trapped between the scrolls and pumped from an inlet 31 to an outlet 33. The axial extent ‘A’ of the trapped volume between the scroll plates is less along a first portion 62 of a flow path 56 between the inlet and the outlet than the axial extent ‘B’ of the trapped volume along a second portion 64 of the flow path, and the first portion is closer to the inlet than the second portion along the flow path.

The half-shell components are assembled together along respective pairs of mutual engaging longitudinal faces and the end stator components are assembled at the ends of the half-shell components at respective pairs of mutual engaging end faces. A longitudinal channel is counter-sunk in at least one longitudinal face of each pair of mutual engaging longitudinal faces for receiving respective longitudinal sealing members for sealing between the half-shell components. Counter-sunk in at least one longitudinal face of each pair of mutual engaging longitudinal faces is a pocket extending transversely from the longitudinal channel for receiving sealant and allowing sealant to flow around a longitudinal sealing member received in the longitudinal channel for preventing the formation of a leakage path.
