    • An improved method for detection of engine faults especially suited for use on ships. The method is in particular related to the detection of a fault in an internal combustion engine having within the housing a crankshaft connected to a piston. The method includes determination of a pressure difference between the housing and the area outside the housing. If comparison of the pressure difference with a fault indicating pressure difference limit shows that the pressure difference is greater than the fault indication pressure difference limit then the presence of the fault is indicated. According to the method is the pressure difference determined by comparing the pressure existing in the housing with the pressure of the area outside the housing, while attenuating pressure changes of the area outside the housing, so that pressure changes having a duration equal to or less than a defined fault characteristic period of time are suppressed.
    • 用于检测特别适用于船舶的发动机故障的改进方法。 该方法特别涉及在壳体内具有与活塞连接的曲轴的内燃机中的故障的检测。 该方法包括确定壳体与壳体外部的区域之间的压力差。 如果压力差与故障指示压差极限的比较表明压差大于故障指示压力差极限,则表示存在故障。 根据该方法,通过将存储在壳体中的压力与壳体外部的区域的压力进行比较来确定的压力差,同时减小壳体外部的区域的压力变化,使得压力变化具有等于或小于 定义的故障特征时间段被抑制。

    • The invention provides an assembly spring (1) and a valve incorporating such a spring. The spring is made from a wire which extends around a longitudinal axis to form windings (4, 5). The spring terminates in axially opposite end portions in first and second end windings. The énd windings each has an arcuate portion wherein the wire extends around the longitudinal axis. The end windings serve to fasten the spring in a groove of an element to which the spring is being attached. The end winding further has a free end portion (6) wherein a free wire end extends outwardly away from the longitudinal axis to form gripping means. The spring thereby facilitates easy attaching of the end winding to the element. In particular, the spring is applicable for attaching a valve element to a plunger in a valve, e.g. a servo valve.
    • 本发明提供一种组装弹簧(1)和结合这种弹簧的阀。 弹簧由围绕纵向轴线延伸以形成绕组(4,5)的导线制成。 弹簧终止在第一和第二端绕组的轴向相对端部。 énd绕组每个具有弓形部分,其中线围绕纵向轴线延伸。 端部绕组用于将弹簧紧固在与其连接的弹簧的元件的槽中。 端部绕组还具有自由端部(6),其中自由线端部从纵向轴线向外延伸以形成夹紧装置。 因此弹簧便于端部绕组容易地附接到元件。 特别地,弹簧适用于将阀元件附接到阀中的柱塞,例如, 伺服阀。

    • The invention provides a system with a pipe and a ventilator forcing a stream of air across an outer surface of the pipe. The pipe is separated by a partition member to form a first and a second conduit for conducting a fluid flow in an upstream and a downstream direction from a heating or cooling system. Due to the separation, it has been facilitated that ventilating devices could be located at various locations along the pipe with substantially equal exchange of thermal energy. The invention could be used for heating or cooling purposes in a building. The invention further provides a method of making such a system and a method of retrofitting an existing system to conduct two oppositely directed streams of a thermally convective fluid for heating or cooling purposes.
