A coil assembly includes: a bobbin; a coil including a winding around the bobbin; a yoke attached to the bobbin; and a connection terminal electrically connected to the winding. The connection terminal is a press-fit terminal that includes a terminal portion projecting perpendicularly from the bobbin outward in an axial direction of the bobbin. The yoke is arranged on a side of the bobbin that is opposite to the terminal portion in an axial direction of the terminal portion, and supports the press-fit terminal.

A system and method for simulating positive train control (PTC) systems in a local and controlled environment using software and hardware. The system can simulate various functionalities of the PTC system in the environment using software and hardware components. The system can instruct the software of a train management computer (TMC) to control electromechanical valves to simulate air compression on brake pipes in response to the PTC system executing a penalty on the locomotive. The system can display statuses of various systems on the locomotive to a user using a cab display unit (CDU). The system can control the software and hardware components to simulate warnings and actions from the PTC system allowing locomotive engineers and conductors to experience the PTC system for optimum training.

A double check valve (100) includes a sleeve (10) with a first inlet opening (11), a second inlet opening (12), an outlet opening (13), and a guide piece (20). The guide piece (20) movable along the longitudinal axis (L) within the sleeve (10), by loading with a fluid-induced pressure, between a first blocking position (S1) and a second blocking position (S2) spaced therefrom, wherein each of the inlet openings (11, 12) is closed at least partly fluid-tightly by the guide piece (20) in one of the blocking positions (S1, S2). The double check valve (100) has a permanent magnet (30, 31, 32, 33), and the guide piece (20) and the permanent magnet (30, 31, 32, 33) are configured to magnetically deflect the guide piece (20) from an intermediate position (Z) arranged between the blocking positions (S1, S2) and/or from one of the two blocking positions (S1, S2).

The disclosure relates to a valve assembly, comprising a valve body, in which a fluid channel is formed that connects a fluid inlet to a fluid outlet, wherein a preload force is applied to a closing body, which is movably mounted in the fluid channel, in the direction of a valve seat formed in the valve body, a fluid force acting on the closing body against the preload force in order to open the valve seat. The closing body is guided axially and/or radially by at least one guide ball, the guide ball being arranged between the closing body and a lateral boundary of the fluid channel.
