Abstract: A drive-in tool (1) for driving fastening means (90) into a workpiece (91), wherein the tool (1) comprises in particular: - a safety device (8) which is coupled with the trigger element (6) and is set up to bring about a transfer of the drive-in tool (1) from a trip-ready state (100) into a secured state (101) after expiry (820) of a delay time which proceeds from an activation (810) of the safety device (8), - wherein the safety device (8) comprises a control volume (15), - wherein the safety device (8) comprises an activation element (33) which is changeable between a first and a second position by means of the trigger element (6), - wherein in the first position of the activation element (33) a first pneumatic connection is defined between the control volume (15) and the gas pressure source connection (23), which is hereafter referred to as charging connection (27.1), - and wherein in the second position of the activation element (33) a second pneumatic connection is defined between the control volume (15) and a pressure sink (40), which is hereafter referred to as discharging connection (33.1), - wherein one connection from the charging connection (27.1) and the discharging connection (33.1) comprises a smallest cross-sectional flow area which, together with a gas pressure of the gas pressure source, determines the delay time of the safety device (8). The invention also relates to a corresponding method for operating a drive-in tool.

Abstract translation: 一种用于将紧固装置（90）驱动到工件（91）中的驱动工具（1），其中所述工具（1）特别地包括：安全装置（8），其与所述触发器元件（6）联接，以及 被设置为在从激活（810）进行的延迟时间的到期（820）之后使驱动工具（1）从跳闸就绪状态（100）转移到安全状态（101） ，其中所述安全装置（8）包括控制容积（15）， - 其中所述安全装置（8）包括激活元件（33），所述启动元件（33）可在第一和第二位置之间通过 触发元件（6）的装置，其中在所述启动元件（33）的第一位置中，在所述控制容积（15）和所述气体压力源连接（23）之间限定第一气动连接，其在下文中被称为 作为充电连接（27.1），并且其中在所述启动元件（33）的第二位置中，在第二气动连接之间限定第二气动连接 控制容积（15）和压力沉降器（40），其在下文中称为排放连接（33.1），其中来自充气连接件（27.1）和排出连接件（33.1）的一个连接件包括最小横截面 其与气体压力源的气体压力一起确定安全装置（8）的延迟时间。 本发明还涉及用于操作驱动工具的相应方法。
