Thank you for your translation. Google translate really sucks :( 
I ended up with this:

  syntax: reset_timedout_connection [on|off]

  default: reset_timedout_connection off

  context: http, server, location

  This directive enables or disables resetting the connection on
  timeout. When resetting the connection, before the socket is closed,
  the socket SO_LINGER option is set with a 0 timeout, which forces a
  RST packet to be sent to the client upon closing the socket, thus
  freeing all memory associated with it. This prevents that a socket
  in the FIN_WAIT1 state keep the buffers associated with it lying
  around.

  Note that sockets with keepalive connections, after the defined
  timeout, are closed in the usual way.

I hope it's clearer and more faithful to the original docs.
