. Inlet pressure labeled as P1, annular passage labeled as P2 that is equivalent to the P1. Diagram 2-18 the working principal drawing of metal piston measurement transducer Diagram 2-18 a: piston 1 reaches the furthest point. The side window of cylinder 1 is entirely opened by piston 1. The oil in the centre oblong chamber flows into the top of piston 4, its pressure P1. At the same time, piston 3 reaches the nearest point, annular groove overlap with the side window of piston 3, making it connected with the elliptical outlet at the upper cylinder. (See diagram 2-17). Meanwhile, Piston 2 impels oil into annular passage and discharge out via the side window of Piston 3 and top elliptical window. In the status, piston 2 and piston 4 lie in cross-bencher position, covering the windows 2 and 4 respectively. Their top pressures are P1 and P2, P1 ＞P2. Owing to the different pressure, piston 2 leaves the center, but piston 4 reaches the center. So do piston 1 and piston 3.

1995. There have undoubtedly been signs of change in cricket and rugby. Where national teams used to be all white, five players of the 13-strong squad going to Sri Lanka are coloured (ie, mixed-race), black or Indian; South Africa s star bowler, Makhaya Ntini, is black. Last year the Springboks, the national rugby team, fielded six black or coloured players in its starting 15, the highest proportion ever, in a match against Australia. By contrast, when the Springboks won the World Cup in 1995, all the players but one were white. Jake White, the coach since 2004, has selected more black players than any of his predecessors and won two-thirds of his matches in the process—though last week s record defeat against Australia left many fans in a state of dazed depression. There are no formal racial quotas in the national teams, but there is a lot of pressure on coaches and selectors to increase black and coloured representation; rugby and cricket are both governed by so-called “transformation�charters. Nonetheless, this is still not enough for many in the ruling African National Congress, who want to see the teams reflect the racial makeup of the country more exactly; whites make up only 9% of the population. In May, Parliament s sports committee lashed out at the rugby authorities for keeping the sport too white and criticised Mr White for not selecting enough black players. The minister of sports, Makhenkesi Stofile, has also complained that sports, and rugby in particular, were not changing fast enough. Bu fuel dispenser t some South African sportsmen think that the people who run sport have now become fuel dispenser oversensitive on this score. The likes of Kevin Pietersen, now a star cricketer for England, and Clyde Rathbone, who plays for Australia s rugby team, complained that formal quotas, imposed at some levels of rugby and cricket until a few years ago, hindered their development. So they took their careers abroad. Some white players fear that selection is increasingly based on skin colour rather th fuel dispenser
