According to one embodiment, a vaporizing system comprises first and second tanks that can accumulate liquid source and first, second, and third pipes. The first pipe allows first gas to be sent out of the first tank. The second pipe allows second gas to be sent out of the second tank. The third pipe is connected to the first and second pipes and allows the first and second gas to be sent out to an external apparatus. The first tank is placed on an upper side of the second tank in a stacked manner.

A system for preventing over pressure in a flexible tank when connected to a water grid that includes the flexible tank and a control unit. An inlet of the tank is connected to the water grid through the control unit. The control unit includes a closed box, an inlet that is connected to the water grid, an outlet that is connected to the inlet of the tank, and a float valve. The user place the flexible tank and set the float so that it will be opened or closed in a certain height of activating water level in the control unit and to place the control unit in a way that the activating water level is at the same level of a desired water level of the flexible tank.

A tanker vehicle for distributing liquid on a surface includes a chassis that supports a tank for holding the liquid. A fluid pump discharges the liquid from the tank and is driven by a hydraulic motor. A hydraulic system delivers hydraulic fluid to the motor through a supply line and returns the fluid to a tank through a return line. A bypass circuit is disposed between the supply line and the return line, bypassing the motor. The bypass circuit includes a system for providing a combination soft start and soft stop of the hydraulic motor that is configured to enable hydraulic fluid to flow from the supply line through the bypass circuit to the return line at a start of the hydraulic system and to flow from the return line through the bypass circuit to the supply line at a shutdown of the hydraulic system.

A waste fluid containment and draining system may have a black waste water holding structure for holding black waste water and a grey waste water holding structure for holding grey waste water. First and second valves may be included for enabling selective emptying of the two holding structures. A macerator pump may be used which has an input in flow communication with both of the first and second valves. A discharge conduit may be in flow communication with an output of the macerator pump. A control subsystem may be in communication with the first and second valves and the macerator pump for controlling the first and second valves, together with the macerator pump, to enable selective pumping out of the holding structures by the macerator pump through the discharge conduit.

A cutting fluid tank includes a variable flow restricting device configured to restrict a flow of cutting fluid containing chips into an interior of a tank body configured to store the cutting fluid containing the chips flowed from a work portion of a machine tool. The variable flow restricting device includes variable partitioning members which constitute at least part of a partitioning that partitions a flow channel of the cutting fluid containing the chips. The variable partitioning member is pivotably and the flow channel varies in association with the pivotal motion of the variable partitioning member.

A baffle for use in a fuel tank has a sidewall and an interior space. The sidewall is formed of a flexible material so as to be radially compressible. The compressibility of the sidewall allows the baffle to be inserted through a hole which is smaller in diameter than the uncompressed diameter of the baffle. The baffle is preferably also longitudinally compressible so that it can be mounted in fuel tanks of varying depths.

A fuel pump module for installation between top and bottom walls of a fuel tank. The housing defines a space accommodating a pump. The fuel pump module includes a mounting component coupled to the housing. The mounting component includes a first surface, a second surface opposite the first surface and facing the housing, a first end, and a second end opposite the first end. The mounting component and the housing are joined with a spring-loaded coupling such that the mounting component is urged away from the housing. The mounting component further includes a U-shaped recess that is concave on the first side of the mounting component. The bottom side of the housing forms a first distal end of the fuel pump module for engaging the bottom wall. The first surface of the mounting component forms a second distal end of the fuel pump module for engaging the top wall.
