    Abstract: A starting valve (100) for a fluid operating machine (200) for a vacuum system (1000). The starting valve (100) comprises: - a valve body (10) with an opening (17) to let a gas in; and an actuating piston (13) splined on a stem (16) free to slide in a guide (18A). The actuating piston (13), with a portion of the valve body (10), defines a chamber (30). The actuating piston (13) is subject to the action of a deformable diaphragm (15). A calibrated throttling hole (16B) is provided in series with a through hole (16A) in line with the stem (16) to establish a fluid communication between the chamber (30) and a fluid-dynamic line (500) of the vacuum system (1000). A shutter (20) is furthermore provided also splined on the stem (16). The shutter (20) closes a gas passage opening (10B) as a function of the pressure difference between the chamber (30) and the fluid-dynamic line (500). The calibrated throttling hole (16B) and the through hole (16A) establish a fluid communication between the space enclosed by a connection (25) and a space (22) defined by a cover element (23) positioned in the upper part of the valve body (10).

    Abstract translation: 一种用于真空系统(1000)的流体操作机(200)的起动阀(100)。 起动阀(100)包括:具有开口(17)以使气体进入的阀体(10); 以及花键连接在引导件(18A)中自由滑动的杆(16)上的致动活塞(13)。 具有阀体(10)的一部分的致动活塞(13)限定腔室(30)。 致动活塞(13)受到可变形隔膜(15)的作用。 校准的节流孔(16B)与与杆(16)成直角的通孔(16A)串联地设置,以在腔室(30)和真空系统的流体动力线(500)之间建立流体连通 (1000)。 此外还提供了一个花键(20),其花键连接在杆(16)上。 挡板(20)根据腔室(30)和流体动力线(500)之间的压力差关闭气体通道开口(10B)。 校准的节流孔(16B)和通孔(16A)在由连接件(25)包围的空间和由位于阀门上部的盖元件(23)限定的空间(22)之间建立流体连通 身体(10)。
