| 摘要 |
<p>The invention relates to a machine (14) for forming thermoplastic containers, comprising at least one moulding unit (16), each moulding unit (16) comprising: - a mould (20) made of at least two half-moulds (20A, 20B), each of which is supported on a carrier (28A, 28B); - at least two fluid-pressure compensating devices (40A, 40B) which are interposed between at least one carrier (28A) and the associated half-mould (20A), and which push the half-moulds (20A) from a pushed-back position into an advanced position in the direction of the other half-mould (20B); - each compensating device (40A, 40B) being connected to a pressurized-fluid source (45) with the interposition of an activation valve (48B), each activation valve (48B) being able to be controlled selectively between an open position and a closed position; characterized in that the activation valves (48B) are automatically actuated valves.</p> |
