Definitions
- the piston 10 is coupled to a coupling rod 12 which is in turn coupled to a crankshaft 1 1 .
- a coupling rod 12 As the crankshaft 1 1 rotates the coupling rod 12 causes the piston 10 to move in a reciprocal manner to and fro within the cylinder 2.
- the actuator means may comprise at least one drive unit.
- Suitable drive means for certain embodiments may be arranged to have a drive member of relatively short stroke, such as a stroke of up to around 10mm, or in the range from around 10 to around 20mm.
- the apparatus is arranged to sense a position of the compression member by detection of a signal generated by a transmitter and received by a receiver following scattering or reflection of the signal by the compression member, the signal being one selected from amongst an optical signal, an acoustic signal and an electromagnetic signal.
- the sensor means may be provided in a substantially fixed location. In some embodiments the sensor means may be provided in the pump body. The sensor means may be provided in a head portion of the apparatus. Other locations are also useful including a portion of the apparatus opposite the head portion.
- the sensor means may be arranged to transmit a signal through the pump chamber towards a face of the compression member that is exposed to the pump chamber volume and to detect a signal scattered or reflected therefrom. Alternatively the sensor means may be arranged to transmit a signal towards a portion of the compression member that is not exposed to the pump chamber volume and to detect a signal scattered or reflected therefrom. In some arrangements this may be a portion of the compression member that is on an opposite side of the compression member to that which is exposed to the pump chamber. This may be a side facing the linear drive means although other arrangements are also useful.
- This feature has the advantage that a mechanical feed-through between volumes at different respective pressures may not be required. This is because the compression member and linear drive means are in fluid communication with one another. Thus in the case that the apparatus is operated as a vacuum pump, the portion of the compression member in fluid communication with the linear drive assembly will share a common vacuum with the linear drive assembly.
- the linear drive means is or comprises a magnetic drive means.
- the magnetic drive means has an electromagnet (which may be or include a solenoid coil) through which an alternating current is arranged to be fed. The alternating current generates an alternating magnetic field by means of which the coupling rod 612 is driven back and forth.
- the inlet valve 633 is actuated by an actuator 633D it is capable of opening by movement of the valve head 633H against the direction of flow of fluid into the cylinder 602 when it is required to allow fluid to pass into the cylinder 602.
- This is in contrast to conventional sprung valves in which displacement of the valve head 633H occurs in the direction of fluid flow due to a difference in pressure between fluid on opposite sides of the head 633H.
- the inlet valve head 633H does not intrude into the cylinder 602 thereby increasing a dead space between the piston 610 and head 603 when the piston 610 is at TDC.
- valve head 633H, 631 H may be moved to abut the valve seat 633A, 631 A and to be urged against the valve seat 633A, 631 A with a relatively high force. If power to the actuator 684, 682 is then terminated the valve head 633H, 631 H will remain urged against the seat 633A, 631 A. This allows a high integrity seal to be formed between the head 633H, 631 H and seat 633A, 631 A to prevent leakage therepast.
- valve head 633H, 631 H may be translated away from the seat 633A, 631 A with a relatively high force if required.
- the position of the piston 610 at a given moment in time may be determined by means of an optical or other sensor.
- the position of the piston 610 may be determined by reference to the piston 610 itself or to the coupling rod 612 which forms part of the piezo- actuated linear drive 668 in the arrangement shown.
- the pump 100 is provided with a cylinder 102 defining a pump chamber 101 within which a piston 1 10 is reciprocally slidable.
- a coupling rod 1 12 is coupled to the piston 1 10 and arranged to be translated to and fro along a longitudinal axis L of the cylinder 102 by a piezo-actuated linear drive 162 provided within a piston drive module 160 (FIG. 3).
