摘要： A leak resistant, switching, double valve system consists of two sliding valve bodies in a valve housing with connecting lines. The two sliding valve bodies, which can be actuated independently of one another, are in contact in the closed position with valve seats in the valve housing, and are located at some distance one behind the other, forming a leak cavity between them. During the opening process, the first sliding valve body, before it leaves its valve seat, while simultaneously reducing the size of the leak cavity, can be placed in contact with the second sliding valve body, which is provided with a tubular extension which exits the valve housing in a sealed manner and connects the leak cavity to the environment of the valve system. With such a double valve system, the invention teaches that an optimal cleaning can be performed with minimal consumption of flushing agent, because the two sliding valve bodies can be moved independently of one another, each by a partial stroke opposite to the direction of the opening motion, into a flushing position, in which the sliding valve body is free from its valve seat and is in contact with a housing stop provided with flushing agent passages.

摘要翻译： 防漏，开关，双阀系统由带有连接线的阀壳体中的两个滑阀体组成。 可彼此独立地致动的两个滑动阀体在关闭位置处与阀壳体中的阀座接触，并且位于一定距离处一个接一个地在它们之间形成泄漏腔。 在打开过程中，第一滑动阀体在离开其阀座之前同时减小泄漏腔的尺寸可以与第二滑动阀体接触，第二滑动阀体设有一个管状延伸部， 阀壳体以密封的方式连接并将泄漏腔连接到阀门系统的环境。 使用这种双阀系统，本发明教导了可以以最少量的冲洗剂进行最佳的清洗，因为两个滑动阀体可以彼此独立地移动，每个通过与开口方向相反的部分行程 运动到冲洗位置，在该冲洗位置中，滑动阀体离开阀座并且与设置有冲洗剂通道的壳体止动件接触。

摘要： A reciprocating saw blade moved in opposite directions parallel to a longitudinal axis is formed with at least one row of longitudinally succeeding teeth having tips all lying on a common tip line parallel to the longitudinal axis and including even teeth all oriented in one direction parallel to the axis and odd teeth alternating with the even teeth and all oriented in the opposite direction parallel to the axis. Each even tooth forms with one of the adjacent odd teeth a double tooth and the tips of the teeth of each double tooth are set laterally of the blade to one side with the lateral set by an offset that alternates longitudinally from double tooth to double tooth to opposite sides of a center blade plane. The offset is the same for all teeth. Each tooth has a relatively steep leading edge and a relatively shallow trailing edge, relative of course to the respective longitudinal direction.
