摘要： The invention is directed to a method and arrangement for checking the operability of a vessel. Pressure is introduced into the vessel utilizing a pressure source having operating variables which vary during operation of the pressure source. These operating variables are detected while the pressure is introduced into the vessel and a conclusion as to a presence of a leak in the vessel is drawn from the operating variables. By utilizing the operating variables, a statement as precise as possible is provided as to the presence of the leak with as little additional equipment as possible.

摘要： A liquid filter (10) with a built-in pressure regulator (11) for fuel is proposed, wherein the pressure regulator (11) with its diaphragm (41) is built on the housing (12) on a component (18) on the front with at least one connection (19). The disk-shaped diaphragm (41) has a single clamping site (39) on its external circumference and a centrally arranged movable closure closure member (42). The diaphragm (41) is acted upon by pressure in a pressure chamber (45) connected with the clean side against the force of a spring (49) in a gas-filled spring chamber (48). The integration of the pressure regulator (11) in the housing (12) permits a simple, compact, cost-effective construction of the liquid filter (10), through whose valve (44) in the pressure regulator (11) only cleaned fuel flows and which is insensitive to backpressure in the tank connection (17).

摘要： The device has a feed pump arranged in the supply tank (12), which can be inserted through an opening (20) in the supply tank (12). The opening (20) is closed by means of a closure element (22) on which a pressure regulator is disposed, which is connected with the pressure side of the feed pump and with the internal combustion engine, and which can be connected with a relief chamber (12). The closure element (22) has a base body (30) made of plastic, in which a depression (40) has been formed, which is closed by means of an elastic diaphragm (52), so that a pressure chamber is formed. A connector (45) projects into the depression (40), which is connected with the relief chamber (12) and whose front end (51) can be closed by means of a flattened ball (74), which is movably seated in a support element (70) connected with the diaphragm (52). The diaphragm (52) is clamped between a retaining element (54) and the base body (30), and the ball (74) is pressed with its flattened area (75) against the front end (51) of the connector (45) by means of a pre-stressed spring (60) acting on the diaphragm (52). When a defined pressure is exceeded in the pressure chamber, the diaphragm (52) is lifted and the ball (74) clears the connector (45) and fuel can flow out of the pressure chamber.

摘要： A control unit (50) makes a single control signal available for driving the through-flow control valves (TEV1, TEV2) (51, 52). Through-flow valve (TEV2) has a larger maximum through flow than through-flow control valve (TEV1). A delay circuit is indicated by the phantom outline (52′) and is mounted at the valve stage TEV2 (52). The delay circuit includes an electric delay element (53) with the aid of which the original control signal is delayed in time by an amount &Dgr;t1 relative to the control signal of control valve (TEV1). The resulting delayed signal is supplied to an AND-gate (54) together with the original control signal. Accordingly, a control signal is present at the output of the AND-gate for the control valve (TEV2). The time delay makes possible the exclusive activation of the through-flow control valve (TEV1) (51) at low pulse duty factors. In this way, a high small quantity meterability is achieved. Starting at a specific pregivable switch-in time, the control valve (TEV2) (52) is switched in so that a very large through flow is possible. The invention thereby makes possible excellent meterability at low as well as at high through flows.
摘要翻译：控制单元（50）使单个控制信号可用于驱动通流控制阀（TEV1，TEV2）（51,52）。通流阀（TEV2）通过流量比通流控制阀（TEV1）具有更大的最大流量。延迟电路由幻影轮廓（52'）表示，并安装在阀级TEV2（52）处。延迟电路包括电延迟元件（53），借助于该延迟元件，原始控制信号相对于控制阀（TEV1）的控制信号在时间上延迟量DELTAt1。所产生的延迟信号与原始控制信号一起提供给与门（54）。因此，控制信号存在于用于控制阀的与门的输出端（TEV2）。时间延迟使得在低脉冲占空因数下独占激活通流控制阀（TEV1）（51）成为可能。以这种方式实现了高的小数量度量。从特定的预先接通时间开始，控制阀（TEV2）（52）被切换，使得可以有非常大的通流。因此，本发明使得在低流量和高通量流量下具有优异的可测量性。

摘要： A liquid filter (1) with a built-in pressure regulator (11) for fuel is proposed, in which the pressure regulator (11) with its diaphragm (32) is mounted on the inside of a cap (14) that has the inflow connector (16) and the tank connector (17). The diaphragm (32), which experiences a flow on its inside, is acted upon by the pressure of the fuel on the clean side (25) of the filter element (21), and the flow through the filter element is radially from the outside inward. Integrating the pressure regulator (11) in the cap enables a simple, compact, economical design of the liquid filter (10), through whose valve (36) in the pressure regulator (11) only cleaned fuel flows.
